Upcoming Colloquia
The Afterlife of Gas Giants: Tidal Disruption and Subsequent Fate of Stripped Cores on Close-in Orbits
Cody Hall, 50 St. George Street
Prof. Heather Knutson
September 16, 2026
2:00pm - 3:00pm
For decades, models have predicted that gas giant planets that come too close to their host stars will be destroyed, with most of their mass accreted onto the host star. However, recent work modeling Roche lobe overflow from close-in gas giants now indicates that angular momentum exchange…
The Beautiful Confusion. The Earliest Galaxies after JWST
Cody Hall, 50 St. George Street
Prof. Andrea Ferrara
September 23, 2026
2:00pm - 3:00pm
One of the major surprises provided by the first months of early Universe observations by JWST has been the detection of a stunning overabundance of luminous, and likely massive, galaxies at redshift z>10. As the first spectroscopic confirmations are accumulating, it is crucial and timely to…
Probing Dark Matter with X-ray Telescopes and the International Axion Observatory (IAXO)
Cody Hall, 50 St. George Street
Prof. Kerstin M. Perez
September 30, 2026
2:00pm - 3:00pm
Axions are among the best motivated candidates for dark matter. Their existence would subtly alter the processes within stellar interiors, imprinting characteristic signals in astrophysical observations. Observations with existing X-ray telescopes have already begun to exploit this connection, placing leading constraints on axion dark matter…

The Icy Origins of Planetary Systems
Cody Hall, 50 St. George Street
Prof. Jennifer Bergner
October 14, 2026
2:00pm - 3:00pm
Planets are born from the gas, dust, and ice present within the disks around young stars. The icy component of the parent disk is profoundly important to the outcomes of planet formation, but prior to JWST there were virtually no observational constraints on ices in…
