ALMA Detects Instabilities in Planet-Forming Disk

A study led by 番茄社区 graduate student Jess Speedie, published in the prestigious journal Nature, has unveiled a key finding in planet formation. By using high-sensitivity data from the Atacama Large Millimeter Array (ALMA), Speedie and the team detected gravitational “wiggles” in the gas disk around the young star AB Aurigae. These wiggles indicate that when disks around young stars become sufficiently massive, they can collapse under their own gravity to form giant planets like Jupiter, confirming predictions of the gravitational instability model.

Discovery of Cosmic 鈥淨uestion Mark鈥� with JWST

The CANUCS team, led by HAA astronomer Chris Willott, has captured an extraordinary image of the galaxy cluster MACS J0417.5-1154 using the James Webb Space Telescope. The cluster's immense gravity bends the light from distant galaxies behind it, producing a stunning gravitational lensing effect. Among these distorted images is a rare cosmic "question mark," created by the light of two interacting galaxies stretched into this remarkable shape. Image credit: NASA, ESA, CSA, STScI, V.

JWST Unveils Dusty Protoplanets Around a Young Star

A team led by UVic grad student Dori Blakely, alongside faculty members Doug Johnstone and Ruobing Dong, successfully utilized the James Webb Space Telescope to capture groundbreaking images of dust around two protoplanets orbiting the young star PDS 70. Using the Canadian-provided NIRISS instrument, the team revealed new insights into exoplanet formation, showcasing UVic's significant contributions to this cutting-edge astronomical research.Image Credit:Blakely et al

Evidence of Planet Formation in Young Star Disks

UVic’s graduate student Camryn Mullin, alongside UVic faculties Ruobing Dong and Doug Johnstone, has harnessed the James Webb Space Telescope to search for forming planets in the disks around young stars. Utilizing Webb’s NIRCam instrument, they investigated HL Tau, SAO 206462, and MWC 758, revealing significant evidence of planetary formation. Their research, published in a series of three papers, highlights the intricate structures within these disks, advancing our understanding of exoplanet formation and positioning UVic at the forefront of astronomical discovery.

Discovery of the Faintest Known Milky Way Satellite
Simon Smith, a graduate student at the 番茄社区, led a team that discovered a new, extremely faint satellite of the Milky Way Galaxy, named “Ursa Major III/UNIONS 1” (UMa3/U1). This discovery was made using images from the multi-observatory UNIONS survey. UMa3/U1, estimated to be 32,000 lightyears from the Sun and 11 billion years old, has a total mass of only about 16 solar masses. The team suggests it could be a remnant of a dwarf galaxy, stripped of most of its mass by the Milky Way.

The ARC

The Astronomy Research Centre (ARC) at the 番茄社区 brings together world-renowned researchers in astrophysics, engineering, computation, and instrumentation working in or near Victoria, BC.

UVic scientists and engineers work closely with colleagues at the nearby Institute in Saanich, the in Penticton, and at in Vancouver, to form one of the largest concentrations of astronomy-related talent in Canada.

Our mission is to communicate the exciting astronomical research being done at/with UVic, to facilitate new collaborations and synergy, to support high quality undergraduate, graduate and post-doctoral training, and to foster public engagement in science.

ARC Director's Corner

kimvenn-resized

Welcome to the UVic Astronomy Research Centre! We were established in 2015 as a communication platform to increase awareness and opportunities in astronomical research at UVic. Our members from UVic’s faculties of Science and Engineering work with researchers at the nearby NRC’s Herzberg Astronomy & Astrophysics Research Centre in Saanich, BC, the NRC’s Dominion Radio Astronomy Observatory in Penticton, BC, the TRIUMF lab in Vancouver, BC, and with industrial partners across Canada.

Members of the ARC include students, postdocs, staff, faculty, adjuncts, and associates involved in a wide range of astronomical research, including ground and space-based instrumentation. All of our work requires research support, through local and national computer servers, rapid access to cloud computing, and high-performance computing for intensive simulations. These are top priorities for the ARC, both to serve our members, and to share the research outcomes from this cluster of excellence across Canada and with the broader community.

ARC hosts or supports local astronomy-related workshops, and helps to coordinate major funding requests and other research initiatives. Currently, ARC hosts an NSERC-CREATE training program on New Technologies for Canadian Observatories (NTCO), it is involved in the CFI-funded GIRMOS instrument being built at NRC-Herzberg for the Gemini-South Observatory, and is part of the large CFI-proposal to contribute to the ANDES high resolution spectrograph at the European Extremely Large Telescope. Members of ARC have been involved in building and commissioning of the new GHOST spectrograph at the Gemini-South Observatory (summer 2022). In addition, several members of ARC are involved in observing programs with the newly launched JWST, as well as the scientific and technical teams designing the Canadian-led CASTOR UV space mission.

Finally, ARC supports UVic activities, such as the observatory open houses and group tours, and student-led initiatives, such the astrophotography group. ARC works to be inclusive of Indigenous ways of knowing, and to be respecful of diverse perspectives in astronomy. This is a pillar in the UVic Strategic Plan, and we hope to provide a more welcoming space for all those who are curious about the sky.

We encourage you to browse these webpages, and explore the exciting research outcomes, research opportunities, and other activities supported by the ARC.
