Title: Strongly Lensed Supernovae: Implications for the Hubble Constant and Transient Astrophysics
Abstract: Strong gravitationally lensed supernovae are exciting laboratories for measuring cosmological parameters and studying supernovae in the high-redshift universe in detail. The "standard clocks" measure time-delay distances, which are an independent route to precision constraints on the Hubble Constant. I will review some of our work on estimating the time-delays and extinction for the first strong lensed Type Ia supernova, iPTF16geu, and SN Zwicky, the first discovery from the Zwicky Transient Facility. In this talk, I will also summarise some of my current work with SN Encore, a cluster-lensed SNIa discovered by JWST and prospects for detecting these events with the Vera C. Rubin Observatory, which will be online imminently.
