Insights into Type Ia Supernovae and Tidal Disruption Events from ASAS-SN

Abstract:

The All-Sky Automated Survey for Supernovae (ASAS-SN), designed as a survey for bright supernovae, has proven to be the premier professional survey project for discovering the brightest and most interesting transient and variable events in the nearby Universe. After expanding and improving our network of telescopes in 2017 and 2018, ASAS-SN now surveys the entire visible sky nightly, allowing us to detect transients earlier and observe them over longer time baselines. In my talk I will discuss recent improvements made to ASAS-SN and the various ways we make our data and discoveries available to the public. I will then discuss my work on resolving the type Ia supernova progenitor problem and on improving our physical understanding of emission from tidal disruption events using recent discoveries from ASAS-SN.
