Radio astronomy has been around for nearly a hundred years. In that time, we have only managed to see a glimpse of the Universe’s many hidden secrets that can be revealed at radio wavelengths. With recent advances in computing, we have seen an explosion of new radio telescopes, including the upcoming Square Kilometre Array for which Canada has officially announced its intention to become a full member. With these telescopes comes a wealth of new and upcoming data. I will discuss some of the things that we hope to learn, the challenges we still face, and the new technology that comes with it.

Space-Based Far-Infrared Telescope – Dr Doug Johnstone

Posted by as UVic Meetings

The Need for a Space-Based Far-Infrared Telescope – Dr Doug Johnstone, NRC

Date/Time: Wednesday December 13th starting at 7:30PM

Location: Bob Wright Centre, Lecture Theatre B150. Park in Lot 1 (pay parking) and cross Ring Road.

Meeting video recording

Far infrared astronomy has been referred to as: the science of the cold, the old, and the dusty. In this talk I will discuss the importance of the far-infrared for astronomy investigations of young stars, distant galaxies, and the granular dirt responsible for rocky planets and, potentially, life! I will give a little history of the space-based missions that have already taken place and provide a glimpse into the difficult task of ensuring a future mission, and Canadian involvement. Along the way I will enumerate the significant complexities of far infrared measurements that lead to the requirement of expensive space-based observatories.

Dr. Doug Johnstone is a Principal Research Officer at NRC Herzberg Astronomy and Astrophysics (HAA) and the NRC; President’s Science Advisor; Adjunct Professor, University of Victoria.

Doug has been an astronomer at HAA for over twenty years, studying star and planet formation with ground and space-based telescopes. For two years he was the Associate Director of the sub-mm James Clerk Maxwell Telescope in Hawaii.

Most recently his research has focused on the mass assembly of young stars, monitoring the brightness changes of deeply embedded protostars from the mid-IR to sub-mm. He also has guaranteed time observations with JWST, searching for forming planets around young stars.

Circumstellar disks – Dr. Brenda Matthews

Posted by as UVic Meetings

“You can’t have one without the other: Circumstellar disks produce and are produced by planets” – Dr. Brenda Matthews, NRC

Many people know that planets form in circumstellar disks around young stars, but did you know that planets later drive the formation of a secondary disk in approximately 1 out of every 5 solar systems? I will present the latest imaging of planet formation and explore the improving possibilities of detecting planets around main sequence stars via the disks they can help create at later times. Using imaging from ALMA and JWST, I will present new discoveries about these more evolved “debris disks” and highlight the potential for future instrumentation to teach us even more.

Date/Time: November 8, 2023, starting at 7:30PM

Location: Bob Wright Centre, Lecture Theatre A104, University of Victoria. Park in Lot 1 (pay parking) and cross Ring Road.

Dr. Brenda Matthews

Dr. Brenda Matthews has a PhD from McMaster University in 2001. From there, she held a postdoctoral fellowship at UC Berkeley before joining NRC in 2004. Since 2019, she has been the Millimetre Astronomy Group Lead and, as such coordinates the MAG support for the ALMA telescope as part of the North American ALMA Science Center. She is an expert in infared,, mm and submm astronomy, polarization imaging and interferometry. Since 2002, much of her research has focussed on debris disks, circumstellar disks around main sequence stars, produced via collisions of comets and asteroids, and she has authored two reviews on debris disks.

She was the PI of a key program on the Herschel Space Observatory, is a member of the disks team of the Gemini Planet Imager Exoplanet Survey and is a member of an Early Release Science team targeting exoplanets and disks with JWST.
