Gilles Fontaine awarded the 2016 CAP Medal for Lifetime Achievement in Physics

It is with great pleasure that the Canadian Astronomical Society / Société Canadienne d’Astronomie recognizes and applauds the awarding by the Canadian Association of Physicists of the 2016 CAP Medal for Lifetime Achievement in Physics to Gilles Fontaine, Université de Montréal, for his pioneering, world-renowned work in theoretical and observational studies of white dwarf stars and the late stages of stellar evolution, including major contributions to the equation of state for white dwarfs and investigations of pulsating compact stars, as well as the discovery of a new class of subdwarf pulsators. His leadership has built what is arguably the preeminent group in the world in this field.

(From the CAP press release:) A true follower of the tradition of excellence in the field of astrophysics in Canada, Professor Fontaine has distinguished himself internationally for the exceptional quality of his research in stellar astrophysics, especially for his study on the final phases of stellar evolution (white dwarfs and subdwarfs, the final products of stellar evolution for most stars). Not only did he build the foundations for an actual theory on the evolution of white dwarfs, he is also one of the pioneers who first used them as cosmochronometers independent from the other components of our galaxy. He also became a true leader in the field of astroseismology, the unique method by which we can examine the internal structure of stars by studying their “starquakes”, using observations and numerical modeling. His work in science, popular worldwide, has earned him multiples prizes and awards.

Victoria Kaspi wins the Gerhard Herzberg Canada Gold Medal

It is with great pleasure that the Canadian Astronomical Society / Société Canadienne d’Astronomie recognizes and applauds the selection of Dr. Victoria M Kaspi of McGill University in Montreal, Canada to receive the Gerhard Herzberg Canada Gold Medal for Science and Engineering from the Natural Sciences and Engineering Research Council of Canada.

Dr. Victoria M. Kaspi is one of the world’s leading experts on neutron stars, the ancient remnants of the most massive stars in the Milky Way. The most massive stars end their lives as black holes. Less massive stars, however, leave behind celestial objects no bigger than the city of Montreal, yet so dense that just one teaspoon would weigh 100 million metric tonnes.

Dr Kaspi uses the largest and most powerful radio and X-ray telescopes in the world to study the physical behaviour of neutron stars, pulsars and magnetars (neutron stars with very strong magnetic fields). Her seminal research sheds light on how stars evolve, how they die and, ultimately, the very nature of matter under extreme conditions.
Dr Kaspi’s research group has had major impacts in the field of astrophysics, including unique tests confirming Einstein’s long-held theory of general relativity and discovering the fastest rotating star. Her team’s landmark discovery of powerful X-ray bursts from an enigmatic class of stars (a finding that essentially doubles the number of known magnetars in our galaxy) was published in Nature in 2013.

Dr Kaspi received her PhD from Princeton University in 1993. She has received numerous prizes and fellowships, including the Hubble Fellowship, the Annie Jump Cannon Prize of the American Astronomical Society, and has been elected as a fellow of the Royal Society of Canada, the Royal Society of London, and the US National Academy of Sciences.

CASCA congratulates Dr. Kaspi for this well earned recognition of her outstanding contributions to cosmology and to Canadian scientific excellence.

VLA Reveals Spectacular “Halos” of Spiral Galaxies

A study of spiral galaxies seen edge-on has revealed that “halos” of cosmic rays and magnetic fields above and below the galaxies’ disks are much more common than previously thought.

Composite image of an edge-on spiral galaxy with a radio halo produced by fast-moving particles in the galaxy’s magnetic field. In this image, the large, grey-blue area is a single image formed by combining the radio halos of 30 different galaxies, as seen with the Very Large Array. At the center is a visible-light image of one of the galaxies, NGC 5775, made using the Hubble Space Telescope. This visible-light image shows only the inner part of the galaxy’s star-forming region, outer portions of which extend horizontally into the area of the radio halo.

An international team of astronomers used the Karl G. Jansky Very Large Array (VLA) to study 35 edge-on spiral galaxies at distances from 11 million to 137 million light-years from Earth. The study took advantage of the ability of the VLA, following completion of a decade-long upgrade project, to detect radio emission much fainter than previously possible.

“We knew before that some halos existed, but, using the full power of the upgraded VLA and the full power of some advanced image-processing techniques, we found that these halos are much more common among spiral galaxies than we had realized,” said Judith Irwin, of Queen’s University in Canada, leader of the project.

Spiral galaxies, like our own Milky Way, have the vast majority of their stars, gas, and dust in a flat, rotating disk with spiral arms. Most of the light and radio waves seen with telescopes come from objects in that disk. Learning about the environment above and below such disks has been difficult.

“Studying these halos with radio telescopes can give us valuable information about a wide range of phenomena, including the rate of star formation within the disk, the winds from exploding stars, and the nature and origin of the galaxies’ magnetic fields,” said Theresa Wiegert, also of Queen’s University, lead author of a paper in the Astronomical Journal reporting the team’s findings. The paper provides the first analysis of data from all 35 galaxies in the study.

To see how extensive a “typical” halo is, the astronomers scaled their images of 30 of the galaxies to the same diameter, then another of the authors, Jayanne English, of the University of Manitoba in Canada, combined them into a single image. The result, said Irwin, is “a spectactular image showing that cosmic rays and magnetic fields not only permeate the galaxy disk itself, but extend far above and below the disk.”

The combined image, the scientists said, confirms a prediction of such halos made in 1961.

Along with the report on their findings, the astronomers also are making their first batch of specialized VLA images available to other researchers. In previous publications, the team described the details of their project and its goals. The team has completed a series of VLA observations and their latest paper is based on analysis of their first set of images. They now are analyzing additional datasets, and also will make those additional images available to other scientists when they publish the results of the later analyses.

With the data from their study made public, “others can do their own analysis to explore other aspects of these halos and what they can tell us about galaxies and their evolution,” said Marita Krause of the Max-Planck Institute for Radioastronomy in Bonn, Germany.

The data are available at: http://queensu.ca/changes

CFHT data helps New Horizons navigate toward Pluto

Launched January 19 2006, the New Horizons spacecraft is now getting very close to Pluto with a predicted closest approach on Tuesday July 14 at 11:49:57 UTC, 01:00 HST. This will be the first human encounter with the Plutonian world. New Horizons will get there relying on CFHT data.

New Horizons is roughly 2.5 meters (8 feet) across and weighed approximately 480 kilograms (1,050 pounds) – about half a ton – when first fueled. It travels a the tremendous Earth-relative speed of about 16.26 kilometers per seconds (58,536 km/h; 36,373 mph). At this speed however, New Horizons will only be able to make a flyby close to Pluto and will not be able to enter orbit. Entering orbit would mean that operators would have to reduce the craft speed by over 90%, which would require more than 1,000 times the fuel that New Horizons can carry.

Nevertheless, a series of maneuvers are needed for a collisionless approach to Pluto so an accurate mapping of the objects close to or in the Plutonian system is crucial. In order to achieve this, the New Horizons team performed several images scans for smaller objects, for both intrinsic scientific interest, and as potential collision hazards. However, in order to enable the hazard search, New Horizons required a high-precision flux/position reference system.

CFHT discretionary time awarded to JJ Kavelaars at the CADC in 2014 turned out to be the best dataset to do just that. During the 2014A semester, Kavelaars and collaborators used MegaCam to refine Pluto’s astrometric system, improving our knowledge of Pluto’s orbit and aiding the New Horizons pre-encounter hazard search team. The catalog resulting from these observations allows more precise calibration than any other wide field imager currently in operation due to the decade long use of MegaPrime on CFHT and the precise calibration system developed for this camera by Stephen Gwyn at the CADC. CFHT/MegaPrime astrometric reference catalogue is now being fed directly into the navigation process for guiding New Horizons into it’s final encounter with the Pluto system.

The Canadian Astronomical Society Delighted by Canada’s Commitment to Construction Funding for the Thirty Meter Telescope

VANCOUVER, April 6, 2015 – The Canadian Astronomical Society (CASCA) is delighted by Canada’s commitment to construction funding for the Thirty Meter Telescope (TMT) international partnership, announced yesterday evening by Prime Minister Stephen Harper at the H. R. MacMillan Space Centre in Vancouver.

“The TMT is the top priority in Canada’s Long Range Plan for Astronomy and Astrophysics, our roadmap to continued international leadership in this field. Canada’s astronomers will point to today’s announcement for decades to come as a critical moment in furthering our excellence in the field,” said Christine Wilson, President of CASCA and Co-Chair of the Coalition for Canadian Astronomy.

The TMT is a revolutionary telescope conceived and designed by Canadian astronomers and industry working together with their partners in China, India, Japan, the University of California and the California Institute of Technology. The TMT will be almost 100 times more powerful than the current best telescope. The telescope will examine the first stars to form in the universe, the black hole at the centre of the Milky Way and the atmospheres and other properties of planets within the habitable zones of other stars.

“Canada has consistently ranked among the top three countries in the world in Astronomy and Astrophysics, and that success is directly linked to our ability to access the top facilities in the world, like the TMT. This is a great day for Canadian astronomy as we have now secured long-term access to what will be the world’s most powerful ground-based telescope,” stated Wilson.

CASCA joined with its Coalition for Canadian Astronomy partners from the university sector and industry in welcoming the Prime Minister’s announcement.

“Canadian astronomers have been responsible for some of the greatest discoveries in this field, and it is our hope that the TMT will inspire a new generation of young Canadians to pursue a career in the sciences. The science TMT will deliver will be transformative for astronomy, both in Canada and around the world. This is a once-in-a-generation project in which all Canadians can take great pride,” said Ray Carlberg, Canadian TMT Project Director.

About the Canadian Astronomical Society / Société canadienne d’astronomie
The Canadian Astronomical Society was founded in 1971 and incorporated in 1983 as a society of professional astronomers. The society is devoted to the promotion and advancement of knowledge of the universe through research and education.

Birth of Planets Revealed in Astonishing Detail in ALMA’s ‘Best Image Ever’

Astronomers have captured the best image ever of planet formation around an infant star as part of the testing and verification process for the Atacama Large Millimeter/submillimeter Array’s (ALMA) new high-resolution capabilities.

This revolutionary new image reveals in astonishing detail the planet-forming disk surrounding HL Tau, a Sun-like star located approximately 450 light-years from Earth in the constellation Taurus.

ALMA uncovered never-before-seen features in this system, including multiple concentric rings separated by clearly defined gaps. These structures suggest that planet formation is already well underway around this remarkably young star.

“These features are almost certainly the result of young planet-like bodies that are being formed in the disk. This is surprising since HL Tau is no more than a million years old and such young stars are not expected to have large planetary bodies capable of producing the structures we see in this image,” said ALMA Deputy Director Stuartt Corder.

All stars are believed to form within clouds of gas and dust that collapse under gravity. Over time, the surrounding dust particles stick together, growing into sand, pebbles, and larger-size rocks, which eventually settle into a thin protoplanetary disk where asteroids, comets, and planets form.

Once these planetary bodies acquire enough mass, they dramatically reshape the structure of their natal disk, fashioning rings and gaps as the planets sweep their orbits clear of debris and shepherd dust and gas into tighter and more confined zones.

The new ALMA image reveals these striking features in exquisite detail, providing the clearest picture to date of planet formation. Images with this level of detail were previously only seen in computer models and artist concepts. ALMA, living up to its promise, has now provided direct proof that nature and theory are very much in agreement.

“This new and unexpected result provides an incredible view of the process of planet formation. Such clarity is essential to understand how our own Solar System came to be and how planets form throughout the Universe,” said Tony Beasley, director of the National Radio Astronomy Observatory (NRAO) in Charlottesville, Virginia, which manages ALMA operations for astronomers in North America.

HL Tau is hidden in visible light behind a massive envelope of dust and gas. Since ALMA observes at much longer wavelengths, it is able to peer through the intervening dust to study the processes right at the core of this cloud. “This is truly one of the most remarkable images ever seen at these wavelengths. The level of detail is so exquisite that it’s even more impressive than many optical images. The fact that we can see planets being born will help us understand not only how planets form around other stars but also the origin of our own Solar System,” said NRAO astronomer Crystal Brogan.

ALMA’s new high-resolution capabilities were achieved by spacing the antennas up to 15 kilometers apart. This baseline at millimeter wavelengths enabled a resolution of 35 milliarcseconds, which is equivalent to a penny as seen from more than 110 kilometers away.

“Such a resolution can only be achieved with the long baseline capabilities of ALMA and provides astronomers with new information that is impossible to collect with any other facility, including the best optical observatories,” noted ALMA Director Pierre Cox.

These long baselines fulfill one of ALMA’s major objectives and mark an impressive technological and engineering milestone. Future observations at ALMA’s longest possible baseline of 16 kilometers will produce even clearer images and continue to expand our understanding of the cosmos.

“This observation illustrates the dramatic and important results that come from NSF supporting world-class instrumentation such as ALMA,” said Fleming Crim, the National Science Foundation assistant director for Mathematical and Physical Sciences. “ALMA is delivering on its enormous potential for revealing the distant Universe and is playing a unique and transformational role in astronomy.”

On-Site Construction Begins on the Thirty Meter Telescope in Hawaii; Watch Worldwide by Webcast on October 7

On October 7, 2014, a groundbreaking and blessing ceremony for the next-generation Thirty Meter Telescope (TMT) will launch a multi-national $1.4 billion project near the summit of Mauna Kea, Hawaii.

Although access to the TMT construction site will be limited due to the area’s sensitive environment and harsh physical conditions, the ceremony will be fully accessible via a live-stream webcast.

George Takei, noted actor, director and author, known for his role in the television series Star Trek, will present pre-recorded science segments during the live webcast. Dr. Robert Hurt, researcher, science podcaster and lecturer, will host the webcast, available at tmt.org/buildingTMT .

Next-Generation Discoveries from a Next-Generation Observatory

“This is an exciting moment as we begin construction of TMT. Its giant mirror, nearly 100 feet across, promises the highest definition views of planets orbiting nearby stars and the first stars and galaxies in the distant universe,” said Edward Stone, Executive Director, TMT International Observatory.

The TMT International Observatory (TIO) is an international partnership with members comprised of the California Institute of Technology, the National Astronomical Observatories of the Chinese Academy of Sciences, the National Institutes of Natural Sciences in Japan, and the University of California. India recently received approval from the Union Cabinet of India to join the TMT project this fall, and Canada is aiming to join as a member in spring 2015.

Initial activities in Hawaii include site preparation and grading, and offsite work has begun in earnest as well. In China, partners are designing the telescope’s fully articulated main science steering mirror system and developing the laser guide star system. Japan has produced over sixty special zero thermal-expansion glass mirror blanks for the main mirror and is designing the telescope structure in detail. Fabricating the mirror support system is ongoing in India. The adaptive optics facility is in final design and the enclosure is ready for construction in Canada. The mirror control system is in final design in California.

“With profound respect for the culture, environment, and values, and thanks to the people of Hawaii, we appreciate the opportunity to build this revolutionary facility for expanding our understanding of the universe,” said TIO Board Chair Henry Yang. “This is a remarkable partnership among institutions in five nations, in cooperation with the University of Hawaii, to achieve a shared, visionary goal. We are grateful for the hard work and outstanding support of so many, including the Gordon and Betty Moore Foundation, over the past decade to reach this important and meaningful milestone.”
