New frontiers in strongly lensed supernova studies with JWST and the Vera C. Rubin Observatory
- 👤 Speaker: Suhail Dhawan

- 📍 Venue: The Hoyle Lecture Theatre + Zoom
Abstract
Strongly lensed supernovae are excellent laboratories for measuring cosmological parameters and studying supernova astrophysics in the high-redshift universe. After reviewing some recent results from ground-based surveys on discoveries of Type Ia supernovae lensed by field galaxies, I will summarise results from two new SN discoveries from JWST : SN H0pe and SN Encore. I will present first constraints on the Hubble constant from a lensed Type Ia supernova and ongoing work on supernova progenitor evolution using SN Encore. Finally, I will conclude with detailed predictions for Vera C. Rubin Observatory’s Legacy Survey of Space and Time.
