Nouvelles de l’Office Gemini Canadien

par Eric Steinbring (Office Gemini Canadien, Centre de Recherches Herzberg en Astronomie & Astrophysique du CNRC) avec la contribution de Stéphanie Côté
(Cassiopeia – hiver 2022)

Expansion du OGC et à Gemini

Après 15 ans de leadership solide et dévoué de l’OGC, Stéphanie Côté a passé le relais et a quitté le rôle de Chef de groupe. Je vais maintenant assumer ce rôle et remercier Stéphanie pour ses années de fidèles conseils et de supervision. Elle restera membre du OGC, et avec Tim Davidge et Joel Roediger, nous sommes maintenant rejoints par un nouveau membre de l’équipe OGC: Wes Fraser.

Veuillez consulter les dernières offres d’emploi pour plus de détails et les dates de clôture.

Progrès du EPDA

Le semestre 2023A était le troisième semestre pour lequel on demandait au Canada de rédiger les demandes de manière anonyme suivant le processus d’examen par les pairs en double aveugle (EPDA). Au cours de chacun de ces trois semestres, le taux de réussite des demandes dirigées par des femmes a été supérieur à celui des demandes dirigées par des hommes, ce qui ne s’était jamais produit au cours des 6 années précédentes pour lesquelles nous avions surveillé cela. La différence de taux de réussite entre les demandes dirigées par des femmes et celles dirigées par des hommes s’est réduit, comme attendu car éventuellement ces taux devraient osciller autour de zéro.

C’est très important que les Canadiennes se familiarisent avec les consignes du EPDA, car de nombreux autres observatoires ont ces mêmes exigences pour leurs demandes (NASA, ALMA, ESO, entre autres) et pourraient rejeter une demande non-conforme au EPDA.

Nous avons été ravis de constater que la grande majorité des demandes Gemini pour 2023A ont suivi avec succès les consignes du EPDA, mais nous avons tout de même reçu 6 demandess qui ne l’ont pas fait (= 19 % des demandes). Ces demandes ont fait un effort pour suivre le EPDA, mais comportaient une erreur mineure. Ce dérapage mineur s’est toujours produit dans le même contexte, c’est-à-dire en se référant à certaines de leurs observations précédentes, ou à d’autres programmes acceptés à d’autres télescopes. Nous vous rappelons de nouveau comment rédiger des textes siuvant le EPDA dans ces situations:

  • Ne faites pas référence à vos programmes d`observations précédents que ce soit à Gemini ou ailleurs, d`une façon qui vous identifierait. Remplacez « Nous avons observé cette galaxie dans notre précédent programme 2022A », dites plutôt « GN-2022A-Q33 a observé cette galaxie précédemment », sans vous approprier le programme, c’est-à-dire ne dites jamais « Notre programme GN-2022A-Q33 ».
  • Il en va de même si vos cibles sont sélectionnées par l’un de vos sondages précédents ou en cours à un autre observatoire ou sont des cibles d’opportunité à déclencher par les données d’un autre de vos programmes. Remplacer « Nos cibles ont été sélectionnées à partir de nos données d`imagerie à 1,45 micron avec WIRCAM de cette région de formation d’étoiles réalisé par notre programme 21BC08 », dites plutôt « Nos cibles ont été sélectionnées à partir des données d`imagerie à 1,45 microns avec WIRCAM de cette région de formation d’étoiles du programme 21BC08 ».
  • Et il en va de même si vous devez vous référer à une demande acceptée à un autre observatoire pour laquelle vous n’avez pas encore reçu de données. Remplacez « Ces données viendront compléter nos données NIRSPec de notre programme JWST accepté 1686 PI = Gagnon », dites simplement « Ces données viendront compléter les données NIRSpec qui seront obtenues par le programme JWST 1686». Parlez de ce programme de façon neutre, sans vous l`approprier.

Dans tous ces cas, lorsque c’est écrit de manière anonyme de cette façon, cela ne dévoile pas si vous êtes le PI ou le Co-I de cet autre programme précédent/futur, ou si vous avez un arrangement avec un co-I pour obtenir les données, ou peut-être vous êtes simplement prêts à fouiller les archives lorsque les données seront rendues publiques.

Veuillez vous assurer de consulter la page ‘Consignes pour EPDA’ pour vos futures demandes Gemini, et n’hésitez pas à nous consulter (OGC à avant la date limite en cas de doute ou de questions.

Nouvel instrument, nouvelles opportunités

Le spectrographe optique de haute résolution pour Gemini (GHOST) est maintenant actif à Gemini-Sud et achève sa phase de mise-en-service. C’est une grande étape, suivant une piste bien rodée d’expertise canadienne en spectroscopie optique à haute résolution, suivant le succès du Gemini Remote Access to CFHT ESPaDOnS Spectrograph (GRACES) à Gemini-Nord. GRACES est également alimenté par fibre optique, connectée à cet instrument du télescope Canada-France-Hawaii. Cette année encore, un communiqué de presse de Gemini a mis-en-évidence un courant de vielles étoiles détectées, via GRACES, au bord de la Galaxie comme étant un amas d’étoiles « déchiqueté »: C-19. D’après ce communiqué de presse: « GRACES a fourni les indices critiques que C-19 est un amas globulaire perturbé et non une galaxie naine perturbée qui est le cas le plus souvent », a expliqué Kim Venn de l’Université de Victoria, la chercheuse principal des observations GRACES. « Nous savions déjà qu’il s’agissait d’un courant d’étoiles très pauvres en métaux, mais pour l’identifier comme étant un amas globulaire nécessitait des métallicités de précision et des abondances chimiques détaillées uniquement disponibles avec des spectres de haute résolution. »

Vous avez de grandes idée? Gemini lance un appel pour des lettres d’intention pour des demandes longues et larges, qui débuteront au semestre 2023B. Les lettres doivent être envoyées au plus tard le 13 février 2023. La date limite pour les demandes complètes sera le 1er avril 2023. Veuillez consulter l’appel de demandes officiel pour plus d’informations, y compris toutes les ressources disponibles sur les instruments ici. N’oubliez pas le programme Retour Rapide! La prochaine échéance sera à midi, heure normale d’Hawaï, le 31 décembre 2022; dans le Sud, vous pouvez demander GMOS-S (Gemini Multi-Object Spectrograph) et F2 (Flamingos 2), disponibles pour la majeure partie de ce cycle à venir, tandis que IGRINS (Immersion Grating INfrared Spectroph) et Zorro (imagerie de speckles) devraient être disponible pendant au moins une partie de cette période. Les dernières nouvelles de Gemini-Nord, qui était en arrêt pour maintenance réguliere depuis le 10 octobre, mais hors ligne depuis plus longtemps en raison d’un incident lors de la maintenance du miroir, est que l’Observatoire prévoit d’achever les réparations en janvier. Il devrait reprendre ses opérations de nuit vers la fin février; les programmes du semestre 2023A ont été planifiés pour s’adapter à cela.

McGill Space Institute Postdoctoral Fellowships

We invite applications for multiple postdoctoral fellowship applications at the McGill Space Institute (MSI).

MSI is an interdisciplinary research centre within McGill University consisting of 20 affiliated faculty members from the Departments of Physics, Earth and Planetary Sciences, Atmospheric and Oceanic Sciences, and Natural Resource Sciences at McGill ( Research topics include (but are not limited to) astrophysics, cosmology, astrobiology, geophysics, life in extreme environments, and the search for extraterrestrial biosignatures.

We anticipate offering multiple positions tailored to the successful applicants’ research interests. MSI Fellowships can be held at any MSI-affiliated department by researchers who specialize in any of the above areas or some interdisciplinary combination thereof.

The successful applicant will have a background in either theoretical, observational, experimental, or computational research in any of the MSI’s research areas. Postdoctoral fellows will work within the research group(s) of one or more faculty members at McGill. Applicants are strongly recommended to contact potential supervisors ahead of time; while not strictly required, most successful candidates in the past have done so.

Applicants should submit a cover letter, a curriculum vitae including a list of publications, and a research statement, and should arrange for three letters of recommendation to be sent through AcademicJobsOnline ( Extra letters will be disregarded.

A successful cover letter will provide a quick summary of your research background, a brief statement of future research directions, and how this fits into the research at McGill. We value an inclusive community, and thus we (optionally) welcome descriptions of any barriers that you may have faced in your research career, descriptions of community-oriented activities that have contributed to a more equitable and diverse work environment, or plans for such work that you may have as a postdoctoral fellow at McGill.

A successful research statement will describe both your past research as well as your research plans, with the best balance to be determined by the applicant. The research plans should include a description of how they relate to research currently being performed by faculty members at McGill. While we appreciate that the finest nuances of one’s research may be understandable only by experts, applicants are advised to make the broadest strokes of their research (and its significance) understandable to an interdisciplinary selection committee consisting of members coming from the entire breadth of MSI’s research mission. The total length of the research statement should not exceed two pages (including figures), although an additional page of references is acceptable.

This position offers a competitive salary and benefits, and will be for two years with a possible renewal for a third year, dependent on supervisor approval and the availability of funds. Preference is given to applicants within 3 years of the PhD. All application materials, including letters of recommendation, must be received by the deadline of December 1, 2022.

We expect to make first-round offers and to notify the waitlist by late December. Later-round offers will be made after the new year through mid-February.

We also encourage applicants to consider applying for a CITA National Fellowship to be held at McGill. A separation application must be submitted directly to CITA. See for details (deadline: Nov.7).

McGill University is committed to diversity and equity within its community. We welcome applications from: women, Indigenous persons, persons with disabilities, racialized people/visible minorities, ethnic minorities, 2SLGBTQIA* people (sexual orientation and/or gender identity minorities), and others who may contribute to diversification.
