Description of Activity
Gave a presentation on "Old Dogs, New Tricks: Late-time observations of Type Ia supernovae with the Hubble Space Telescope".
Type Ia supernovae (SNe Ia) are famously used to measure distances to faraway galaxies and, in turn, constrain cosmology. However, we still do not know exactly what types of star systems explode as these supernovae or how the explosions occur. Most SNe Ia are only observed for several weeks before they become too faint for most telescopes. Over the last ten years, late-time observations with the Hubble Space Telescope 800-2000 days post explosion have revealed fresh insights into the physics of these SNe. In my talk, I will summarize the discoveries of the last ten years (including a year-long near-infrared plateau!) and discuss their impact on our understanding of these stellar explosions.
