CATAC Update on the Thirty Meter Telescope

By Michael Balogh (CATAC Chair)
(Cassiopeia – Winter/hivers 2017)

The TMT Science Forum was held in Mysore, India on November 7-10. This is the first time one of these meetings took place in India, and it again proved a very effective venue for helping the partner communities become engaged with the project. The focus this year was on TMT instrumentation beyond first light. As announced in the last issue of e-Cass, TMT has issued a call for White Papers due March 21, 2018. These will be reviewed by the SAC, who will make recommendations for the next instrument(s) after first light. The Science Forum provided an opportunity to kick off some of the discussion. Talks are available here. There were also supporting workshops, held on November 6, for discussing three capabilities: a Planetary Science Imager, high resolution spectroscopy, and the first-light instrument WFOS.

At the last SAC meeting, some important updates were provided on both first light instruments for TMT: the infrared imaging spectrograph (IRIS) and the wide-field optical spectrograph (WFOS). In both cases there are decisions being made now, described below, that should be important to the Canadian community. CATAC is therefore following these developments closely.

IRIS successfully completed the second part of its Preliminary Design Review in September; reviews were very positive. The review focused on IRIS observing modes, its interaction with the AO system (NFIRAOS) and the data reduction system. As a result of the review, the IRIS science team is now discussing details of how observations will be taken, and how data will be reduced. NIRIS coupled with NFIRAOS is a very powerful, but complex, instrument that we expect to be of great interest to the Canadian community. If you are interested in knowing more, or would like to get involved, you are strongly encouraged to get in touch with one of the Canadian science team members: Tim Davidge, Pat Coté, or Christian Marois.

WFOS remains a very exciting and challenging instrument. Having earlier abandoned the original concept (MOBIE), the project is now currently considering two very different designs. One would use image slicers, robotically mounted onto masks, to enable multiobject spectroscopy up to high resolution (R~10,000) with narrow slits. The other is a fibre-based design that would allow patrol of the full field, but also bundling to make integral field units. Both designs have advantages and limitations. CATAC will be meeting with the PI of WFOS, Kevin Bundy, on Dec 19 to learn more about the risks and advantages offered by each approach, and the science input driving the specifications. We anticipate that early in 2018 we will be engaging you, the community, to ensure our Science team and SAC members are best able to represent Canadian interests at the time of this important decision.

In addition to these exciting developments, TMT has recently contracted a design study for a secondary adaptive mirror. Studies are underway to predict the improvement in performance as a function of wavelength, natural seeing and field of view. New simulation results will be presented at the next SAC meeting, in Feb 2018. Though this is unlikely to be a first light capability, it could be a priority for an upgrade not long after commissioning.

The political and legal situation in Hawai’i remains generally positive. Legal challenges remain. These are out of our hands and are being dealt with in the courts. The critical issue now is the time it takes to resolve these cases, but the Project remains optimistic that a site decision will be made in April 2018.

To help inform the community on the funding situation facing TMT, on Sept 26 CATAC hosted a public Webex with Ed Stone (Executive Director) and Gary Sanders (Project Manager). Over thirty CASCA members attended. We were presented with a frank and open description of the TMT budget and construction plans. One important takeaway from that meeting was how much impressive work is currently being done, by all partners, despite the delays. About 70% of the items are under contract right now, and roughly 10% of the project is complete. We also got a detailed description of how the project is costed, and how those costs are being revised. There is of course a significant funding gap, that is understood, and the plan submitted to the NSF included a set of options for staging the project. Further discussions with NSF, however, await a site decision.

President’s Message

Professional Climate Survey

Science Minister Kirsty Duncan gave a speech at the Canadian Science Policy Conference in Ottawa on November 2 in which she touched on many topics of interest to CASCA, including some preliminary thoughts on The Fundamental Science review (a.k.a. the Naylor Report), the launch of the Canada Research Coordinating Committee and the recent appointment of Dr. Mona Nemer as the Government’s Chief Science Advisor. As will be described below, CASCA is communicating directly with the government on all these subjects. Another important topic highlighted in her speech was the need for greater representation in the sciences. In her speech, Minister Duncan noted the following:

This issue has a deep personal significance to me as someone who spent the bulk of her career as a woman in science.

During my science career, I was told the reason I was getting paid in the bottom 10th percentile was because I was a woman.

I was asked by a fellow faculty member during a staff meeting when I planned on getting pregnant.

I was asked to choose how I wanted to be treated: as a woman or as a scientist.

My travels across Canada have made it very clear to me that addressing the inequities in the research community must remain a top priority for all of us.

Minister Duncan concludes:

We must work together to right the gender, equity and diversity scales in the sciences. And when we do, science will be that much stronger for it.

I say ‘amen’ to that. In fact, I think we as a society do too. And when it comes to issues of greater inclusiveness and fairness in representation, CASCA as a professional society can have real agency in effecting changes in our own professional climate. We have taken some important steps already (e.g. by forming the Equity and Inclusivity Committee, led by Brenda Matthews), but it would be incredibly helpful to have a clearer understanding of the scope of the problem. For that reason the Equity & Inclusivity Committee put together a climate survey (available in both French and English. All CASCA members should already have received news about the survey via the society’s email exploder, but allow me to reiterate how hugely important this survey is to the health of our profession in Canada. If you don’t believe me, believe the Minister of Science. If you haven’t already completed the survey, please, please, find the time to do it.

Coalition Activities

Since the last time I wrote to you, the Coalition for Canadian Astronomy has continued its dialogue with the federal government, focusing on the priorities set out in the Long Range Plan. On November 28, the co-chairs1 of the Coalition and two invited guests visited Ottawa with this purpose in mind. We had two specific goal for this trip. The first was to provide updates on some key priorities which we have been invited to comment further on during our last visit (progress on the Thirty Meter Telescope and the Square Kilometre Array). The second was to advocate for greater support of the Canadian Space Agency. We met with Dr. Nipun Vats (Assistant Deputy Minister, Department of Innovation, Science and Economic Development) and Michael Rosenblatt (Director, Federal Science and Technology Policy, Science Policy Branch, Department of Innovation, Science and Economic Development). We also met with Katharine Wright at the Office of the Chief Science Advisor, and with Kate Young (M.P., Parliamentary Secretary to the Minister of Science).

To help us articulate our goals more clearly, on this trip we were joined by Prof. Sarah Gallagher (Western University) and by Deborah Lokhorst (a PhD student at the University of Toronto). Sarah recently co-authored an important white paper on space astronomy funding (together with Jeremy Heyl and Ilaria Caiazzo, both at UBC), and she was able to place Canada’s investments in Space Astronomy into a broad international (and historical) context. Deborah was tasked with explaining why federal support is needed now for priority missions identified in the Long Range Plan (such as WFIRST), in order to secure a bright future for younger generations of Canadian astrophysicists, such as herself, that will be carrying the torch once people like me have ridden off into the sunset. While this visit to Ottawa focused largely on Space Astronomy and support for the Canadian Space Agency, we did not fail to communicate how the plan represents a coherent vision for Canadian astrophysics (agreed upon by the whole community), how astrophysics (the country’s premiere science, in terms of international impact) benefits all Canadians, and how the LRP aligns with the government’s priorities.

On behalf of the CASCA Board of Directors, allow me to conclude this message by wishing you all the best for a happy holiday season, and for a productive and prosperous 2018.

1 The coalition co-chairs are Prof. Don Brooks (UBC), representing ACURA (the Association of Canadian Universities for Research in Astronomy), Guy Nelson (CEO of Empire Industries), and me (representing CASCA, i.e. you).

Maunakea Spectroscopic Explorer (MSE) Update

By/par Patrick Hall, MSE Management Group Member
(Cassiopeia – Winter/hivers 2017)

The MSE Project Office has concluded a successful series of subsystem conceptual design reviews which occurred throughout 2017. The design as reviewed is expected to be very capable of achieving the high-level MSE science goals. As a not entirely random example, the site, enclosure, telescope, and wide field corrector optics are expected to deliver 0.51-arcsecond mean R-band seeing to the focal plane at zenith. The MSE Systems Conceptual Design Review will be conducted in January 2018 by a high profile external panel chaired by Michael Strauss (Princeton).

As this newsletter goes to press, the MSE Management Group is about to hold its annual meeting at CFHT Headquarters. The Management Group outgoing chair (Jean-Gabriel Cuby) and the incoming chair (Pat Hall) will join Project Manager Rick Murowinski and Project Scientist Alan McConnachie in reporting to the CFHT Board later that same week. The Management Group will be discussing the pre-construction phase Statement of Understanding to establish the framework within which existing and new MSE partners will proceed with the preliminary design of MSE. To publicize the upcoming preliminary design phase of MSE to existing and potential new partners, an MSE prospectus is being developed and MSE representatives are attending meetings related to wide-field spectroscopy and US decadal survey planning.

Canadian participation in MSE conceptual and preliminary design work to date has focused on the MSE Fiber Transport System. Darren Erickson (NRC Herzberg) and industry partners Fibertech Optica have been working on testing plans for the Fiber Transport System with UVic student interns under the auspices of the NSERC CREATE training program ‘New Technologies for Canadian Observatories’. To support the testing, an NSERC Research Tools & Infrastructure grant has been submitted (PI Venn); results will be known next year. Other support proposals are in the early planning stages; for details, contact Pat Hall.

The MSE website is mse.cfht.hawaii.edu. Questions or comments about MSE governance can be directed to your MSE Management Group Members, Greg Fahlman and Pat Hall. Scientific questions or comments can be directed to your MSE Science Advisory Group Members, Sarah Gallagher and Kim Venn.

BRITE-Constellation Mission Update

By/par Gregg Wade, Canadian PI for BRITE
(Cassiopeia – Winter/hivers 2017)

BRITEpatch

BRITE-Constellation is an international space astronomy mission consisting of a fleet of 20x20x20 cm nanosatellites dedicated to precision optical photometry of bright stars in two photometric colours. The mission continues in full science operations, with 22 data releases to BRITE target PIs having already taken place, and many datasets available in the public domain from the BRITE public archive.

The BRITE mission is a collaboration between Canadian, Austrian and Polish astronomers and space scientists. The Canadian partners represent University of Toronto, Université de Montréal, Bishop’s University, and Royal Military College of Canada. The mission was built and is operated by the University of Toronto Institute for Aerospace Studies Space Flight Lab (UTIAS-SFL). The Canadian Space Agency funded the construction of the Canadian satellites, and continues to fund mission operations.

Operations

There are five operating BRITE satellites in the Constellation, collecting data on various sky fields in a coordinated programme to obtain well-sampled, longterm continuous (~6 months) light curves in both red and blue bandpasses.

As this issue of Cassiopeia went to press, here was the status of the sky assignments for the BRITE cubesats:

  • BRITE Toronto (Canada): Toronto observes with a red filter. It is currently observing the Lac/Cyg field and the Taurus field.
  • BRITE Lem (Poland): Lem observes with a blue filter. It is also observing the Taurus field.
  • BRITE Heweliusz (Poland): Heweliusz observes with a red filter. This satellite is observing Vel/Pic III field, after recently completing a campaign observing the Pegasus field. As implied by the numeral ‘III’, the current campaign on Vel/Pic represents a revisit of a previously-observed field.
  • BRITE Austria (Austria): BRITE Austria observes with a blue filter. It is observing the Cassiopeia II field.
  • UniBRITE (Austria): UniBRITE observes with a red filter. This satellite is currently observing the Vel/Pup IV field.

The BRITE Constellation observing programme from early 2017 through early 2019 has been planned by the BRITE Executive Science Team (BEST), and details are available on the BRITE photometry Wiki page.

Constraining the near-core rotation of the gamma Doradus star 43 Cygni using BRITE-Constellation data” (Zwintz et al. 2017sc, A&A, in press):
Zwintz et al. report that photometric time series of the gamma Dor star 43 Cyg obtained with the BRITE-Constellation nano-satellites allow a detailed study of its pulsational properties, leading to new constraints on its interior structure. They attempt to measure a g-mode period spacing pattern, yielding the near-core rotation rate of 43 Cyg and a redetermination of the star’s fundamental atmospheric parameters and chemical composition. They conducted a frequency analysis using the 156-day-long data set obtained with the BRITE-Toronto satellite and employed a suite of MESA/GYRE models to derive the mode identification, asymptotic period spacing and near-core rotation rate. They also used spectroscopic data to redetermine the fundamental atmospheric parameters and chemical composition of 43 Cyg. They detected 43 intrinsic pulsation frequencies and identified 18 of them to be part of a period spacing pattern consisting of prograde dipole modes. The near-core rotation rate was determined to be frot = 0.56+0.12-0.14 d-1. The atmosphere of 43 Cyg shows solar chemical composition at an effective temperature of 7150 K, a log g of 4.2 and a projected rotational velocity, vsini, of 44 km/s. The morphology of the observed period spacing patterns shows indications of the presence of a significant chemical gradient in the stellar interior.

BRITE-Constellation high-precision time-dependent photometry of the early-O-type supergiant zeta Puppis unveils the photospheric drivers of its small- and large-scale wind structures” (Ramiaramanantsoa et al. 2017, MNRAS, in press):
Ramiaramanantsoa et al. report that BRITE photometric monitoring has revealed two simultaneous types of variability in the O4I(n)fp star zeta Puppis: one single periodic non-sinusoidal component superimposed on a stochastic component. The monoperiodic component is the 1.78 d signal previously detected by Coriolis/SMEI, but this time along with a prominent first harmonic. The shape of this signal changes over time, a behaviour that is incompatible with stellar oscillations but consistent with rotational modulation arising from evolving bright surface inhomogeneities. By means of a constrained non-linear light curve inversion algorithm they mapped the locations of the bright surface spots and traced their evolution. Simultaneous spectroscopic monitoring of the star shows cyclical modulation of its He II 4686 Å wind emission line with the 1.78 day rotation period, showing signatures of Corotating Interaction Regions (CIRs) that appear to be driven by the bright photospheric spots. Traces of wind clumps are also observed in the 4686 Å line and are correlated with the amplitudes of the stochastic component of the light variations probed by BRITE at the photosphere, suggesting that the BRITE observations additionally unveiled the photospheric drivers of wind clumps in zeta Pup and that the clumping phenomenon starts at the very base of the wind. The origins of both the bright surface inhomogeneities and the stochastic light variations remain unknown, but a subsurface convective zone might play an important role in the generation of these two types of photospheric variability.

Results from the First Indigenous Astronomy Workshop at the University of Toronto

By/par Hilding Neilson, CLTA Assistant Professor (U of Toronto)
(Cassiopeia – Winter/hivers 2017)

On November 2 and 3 2017, we held a workshop on the topic of Indigenous astronomy at the University of Toronto. The workshop was sponsored by the Centre for Indigenous Studies, the Dunlap Institute for Astronomy & Astrophysics and the Department of Astronomy & Astrophysics. The purpose of the two-day workshop was to bring together astronomers, educators and Indigenous scholars from around the Greater Toronto region to discuss methods for improving engagement with Indigenous communities and how to be more inclusive in delivering Indigenous knowledge in the classroom. This workshop is part of a larger initiative to develop new curriculum and learning materials around Indigenous astronomy.

More specifically, the goal of the workshop was to address the following three questions:

  • How do we enhance Indigenous knowledge in the astronomy classroom?
  • How do we build connections between astronomer and Indigenous communities?
  • How do we motivate more Indigenous people to participate in STEM and education?

As part of the workshop, we invited speakers from across eastern Canada to lead this discussion. The workshop was opened by Elder Andrew Wesley who related his own personal connections with the sky and nature along with the importance of understanding nature as part of Indigenous culture. This was followed by Professor Melanie Jeffery, who shared about developing the Indigenous Ecology course that is a science breadth course at the University of Toronto. That discussion highlighted the need to understand Indigenous worldview as part of the education process in science along with the tensions between literacy and oral traditions in learning. One of the more interesting topics in the discussion was the role of storytelling in the teaching methodologies that can be incorporated into astronomy teaching as a way to diversify teaching and learning.

Professor Cheryl Bartlett from Cape Breton University and Ms. Carola Knockwood from Mi’kmaw Kina’matnewey presented talks around the concept of Two-Eyed Seeing in science. This concept was highlighted in the Naylor report on science as a way to connect research in the academic sphere with First Nations knowledge systems and perspectives. Both speakers discussed the value of Two-Eyed Seeing for health and biological sciences and how astronomers might consider applying this philosophy. Ms. Knockwood also discussed how Eurocentric knowledge methods used in academia are not necessarily serving Indigenous learners because of how Universities tend to be disconnected from traditional Indigenous knowledge.

We also heard from Mr. Frank Dempsey from the Royal Astronomical Society of Canada who has spent years sharing Indigenous astronomy stories with the public and Dr. David Pantalony from the Canadian Museum of Science and Technology. Mr. Dempsey discussed various stories from the Mi’kmaw tradition of Muin and the Seven Hunters along with stories about constellations that are similar to Orion and the Pleiades. Dr. Pantalony presented a discussion on a new exhibit at the museum centred on Indigenous sky knowledge that was co-curated with Prof. Annette Lee from St. Cloud State University and Mr. Wilfred Buck from the Manitoba First Nations Education Resource Center as an initial step to including Indigenous knowledge in science outreach.

Along with the talks, a significant fraction of time of the workshop was dedicated to discussion of the three key questions and to develop strategies for engagement with Indigenous knowledge and Indigenous communities. In particular, three important lessons are:

  1. We, as astronomers, should work to interact with and learn from Elders and knowledge keepers on their terms. Many Elders want to share their knowledge and see it used respectfully and earnestly.
  2. When we discuss Indigenous knowledge in the classroom it should be done in context. That discussion should acknowledge the place of that knowledge in Indigenous life. This context includes discussion of culture, prejudice and the impact of colonization. While this discussion is challenging we cannot simply discuss Indigenous astronomy without discussing Indigenous culture and history.
  3. In various talks, stories were related about how university/college education requires Indigenous students to think in terms of western knowledge system that treats their own knowledge as less valuable. This settler mentality creates added stress for Indigenous student wishing to pursue advanced education. One way to encourage more Indigenous students is to build community connections that encourage working in both western and Indigenous knowledge systems.

This workshop and public discussion was the first step in developing curriculum for astronomy courses around Indigenous content and developing strategies for collaborating and serving Indigenous communities in Canada. This initiative is important as our astronomy courses do not reflect the diversity of the nation and ignores the contributions of Indigenous knowledge. It is the hope of those involved with this workshop that it be the first workshop of many and helps move forward the national conversation the astronomy community needs to have about delivering and including Indigenous astronomy knowledge in the classroom.

Grab some Fast Turnaround Time!

Contrary to popular belief, the Fast Turnaround proposals do not need to be urgent to qualify for this program. The FT program is designed to be used to conduct pilot studies, complete data sets, and follow up newly-discovered objects, basically any kind of project with scientific value that you can think of.

The way it works is that users submit proposals at the end of each month. Proposals are then peer-reviewed by the PIs of the submitted proposals in the following couple of weeks. The successful programs are activated a couple of weeks later and stay active in the queue for 3 months.

Canada has not been using much of its share of allocated FT time so far, so we encourage Canadians to apply for FT time; there is lots of time to grab! Both Gemini North and South accept FT proposals.

The next Gemini FT deadline is at 23:59 Hawaiian Standard Time on December 31.

For full details about the program, including the latest Call for Proposals, see the FT web pages.

To receive monthly deadline reminders and news of changes to the program, send a message to Gemini-FT-reminders+subscribe.

Gemini Remote Observing Station in Victoria

Last September we inaugurated our new Gemini Remote Observing Station installed here on the hill, which enables observations using GPI on Gemini-South to be done remotely and entirely controlled through a VNC link. The Gemini Remote Observing station consists of two powerful Dell tower workstations and a total of 10 monitors. It is installed in one of the ground floor rooms in the “White House” on Observatory Hill close to the DAO telescopes (which used to be first DAO director John Plaskett’s residence, but had been converted to offices decades ago). Such remote observing facilities connecting to Gemini only exist in Stanford and Berkeley so far, to help the GPI campaign team support their numerous observing runs. The Canadian Gemini Office becomes the first National Gemini Office with such a remote observing facility. Christian Marois with University of Victoria students Ben Gerard, Zach Draper and postdoc Celia Blain succeeded in September for the first time to connect via VNC to GPI at Gemini-South and take control of the instrument and take the first data (imaging nearby stars to search for extrasolar planets) for the GPI campaign program. Two other successful observing runs were conducted by the team in early November and late November.

Our hope is that in the future this remote observing station could evolve to be able to connect to other current Gemini instruments. It could help the training of local students in giving them ample exposure to observing at a large telescope. Eventually it could also be offered to Gemini Large Programs teams in the Canadian community for their Gemini Priority Visiting observations, saving them the expense of travelling to Hawai’i or Chile. In the future it will also be useful for the commissioning of GHOST, the future Gemini High-Resolution Optical Spectrograph, built in part by HAARC.

Recent Canadian Gemini Press Releases

  • Clare Higgs (University of Victoria) is one of the numerous co-Is on the Gemini papers from the first-ever detection of optical and infrared light linked to a gravitational wave event. The gravitational wave event GW170817 was detected by LIGO (Laser Interferometer Gravitational-Wave Observatory), Virgo, and the Fermi Gamma-ray Space Telescope on August 17, 2017. Gemini was one of the first telescopes to capture the first infrared photons ever seen from this neutron-neutron star merger, a so-called kilonova. Gemini provided more data than any other telescopes following the fading object over 25 nights with imaging and spectroscopy data. The Gemini spectra showed directly that the neutron star binary merger formed and dispersed heavy elements, like gold and platinum, into space. This solves the decades-long mystery of the origin of the heaviest elements. The Gemini press release is here.
  • G-IRMOS got funded by the Canadian Foundation for Innovation! This is a future Gemini visitor instrument, meant to be a TMT pathfinder. It will consist of multiple deployable IFU (4) over a 2×2 arcmin field using Multi-Object Adaptive Optics (MOAO) fed by GeMs. It will be geared for JWST follow-ups, for the study of star formation, metallicity and kinematics of high-z galaxies, stars & planet formation within our Milky Way, and supermassive black holes in nearby galaxies. The PI is Suresh Sivanandam at Dunlap Institute, with a team of over 20 astronomers distributed in 6 canadian universities. You can view the press release from the Dunlap Institute here.

Sautez sur du temps de Retour Rapide!

Contrairement à la croyance populaire, les demandes de Retour Rapide (=Fast Turnaround) n’ont pas besoin d’être urgentes pour être admissibles à ce programme. Le programme RR est conçu pour être utilisé pour mener des études pilotes, compléter des ensembles de données ou suivre des objets nouvellement découverts, bref tout type de projet ayant une valeur scientifique que vous pouvez imaginer.

La façon que le programme fonctionne est que les utilisateurs/trices soumettent des demandes à la fin de chaque mois. Au cours des deux semaines suivantes, les demandes sont examinées par les chercheur(e)s principaux(ales) des demandes soumises. Les programmes retenus sont activés quelques semaines plus tard et restent actifs dans la queue d’observation pendant 3 mois.

Jusqu’à maintenant le Canada n’a pas utilisé beaucoup de sa part de temps alloué à ce programme, alors nous encourageons les canadien(ne)s à faire une demande de temps RR, il y a beaucoup de temps disponible! Gemini Nord et Sud acceptent tous les deux des demandes RR
.
La prochaine date limite pour le programme RR à Gemini est à 23:59 (heure normale Hawaïenne) le 31 décembre.

Pour plus de détails sur le programme, y compris le dernier appel de demandes, consultez les pages Web de RR ici.

Pour recevoir des rappels mensuels des dates limites et des nouvelles sur les changements apportés au programme, envoyez un message à Gemini-FT-reminders+subscribe.

PIT plus facile que jamais avec l’aide de vidéos

Veuillez noter que le groupe de soutien aux utilisateurs de Gemini a produit une série de courtes vidéos sur YouTube pour vous aider à remplir la Phase1 avec PIT. Il existe une vidéo qui est un tutoriel général sur PIT, mais aussi d’autres vidéos sur des sujets spécifiques tels que comment remplir la section observations, la bande 3 ou la section des requêtes de temps. Vous pouvez voir la sélection complète ici.

Le narrateur de ces vidéos n`est nul autre qu`André-Nicolas Chené, un ancien membre de l`OGC, maintenant à Gemini.

Une Station d’observation Gemini à distance à Victoria

En septembre dernier, nous avons inauguré notre nouvelle station d’observation Gemini à distance installée ici à Victoria, qui permet d’effectuer des observations en utilisant GPI sur Gemini-Sud à distance et entièrement contrôlé par un lien VNC. La station d’observation Gemini à distance se compose de deux puissants postes de travail Dell et d’un total de 10 moniteurs. Elle est installé dans l’une des salles du rez-de-chaussée de la «Maison Blanche» sur la colline de l’Observatoire près des télescopes OFA (qui était la résidence du premier directeur John Plaskett, mais qui a été convertie en bureaux il y a des décennies). De telles stations d’observation à distance se connectant à Gemini n`existent présentement qu`à Stanford et à Berkeley, pour aider l’équipe de la campagne de GPI à soutenir leurs nombreuses missions d’observation. L`Office Gemini canadien devient le premier office national Gemini doté d’une telle station d’observation à distance. Christian Marois et les étudiants de l’Université de Victoria Ben Gerard, Zach Draper et la chercheuse postdoctorale Celia Blain ont réussi pour la première fois en septembre à se connecter via VNC à GPI à Gemini-Sud et à prendre le contrôle de l’instrument pour prendre des données (imagerie d`étoiles proches pour détecter des planètes extrasolaires) pour le programme de campagne GPI. Et depuis deux autres missions d’observation ont été menées avec succès par l’équipe en début novembre et fin novembre.

Nous espérons qu’à l’avenir cette station d’observation à distance pourrait évoluer pour pouvoir se connecter à d’autres instruments Gemini. Cela pourrait aider la formation des étudiants locaux en leur permettant l`accès facile à l’observation sur un grand télescope. Éventuellement, elle pourrait également être offerte aux équipes des Grands Programmes Gemini de la communauté canadienne pour leurs observations en mode Visiteur Prioritaire à Gemini, ce qui leur éviterait de devoir voyager à Hawaï ou au Chili. À l’avenir, elle sera également utile pour la mise en service de GHOST, le futur spectrographe optique à haute résolution de Gemini, construit en partie par HAARC.

Communiqués de presse canadiens récents

  • Clare Higgs (Université de Victoria) est l’une des nombreux co-Is sur les articles Gemini sur la toute première détection de lumière optique et infrarouge liée à un événement d’onde gravitationnelle. L’onde gravitationnelle GW170817 a été détectée par LIGO (Laser Interferometer Gravitational-Wave Observatory), Virgo et le télescope spatial Fermi en rayons Gamma le 17 août 2017. Gemini a été l’un des premiers télescopes à capturer les premiers photons infrarouges jamais vus de cette fusion d’étoiles neutron-neutron, une soi-disant kilonova. Gemini a fourni plus de données que tout autre télescope en suivant l`objet qui s`est éteint lentement pendant 25 nuits avec des données d’imagerie et de spectroscopie. Les spectres Gemini ont montré directement que la fusion binaire des étoiles à neutrons formait et dispersait des éléments lourds, comme l’or et le platine. Cela résout un mystère vieux de plusieurs décennies de l’origine des éléments les plus lourds dans l`espace. Le communiqué de presse Gemini est ici.
  • G-IRMOS a été financé par la Fondation Canadienne pour l’Innovation! C’est un futur instrument visiteur de Gemini, destiné à être un précurseur pour TMT. Il se composera de multiples Unités de Champ Intégrales déployables (4) sur un champ de 2×2 minutes d`arc en utilisant l’optique adaptative multi-objets (MOAO) alimentée par GeMs. Il sera destiné aux suivis JWST, à l’étude de la formation d’étoiles, de la métallicité et de la cinématique des galaxies à haut redshift, de la formation des étoiles et planètes dans notre propre Voie Lactée, et des trous noirs supermassifs dans des galaxies voisines. Le chercheur principal est Suresh Sivanandam de l’Institut Dunlap, avec une équipe de plus de 20 astronomes répartis dans 6 universités canadiennes.
