Title: Identifying the Progenitors of Astrophysical Transients

Abstract: Supernovae (SNe) and other stellar explosions come from a wide variety of stellar systems and in varying environments, but in most cases the connection between progenitor systems and the resulting explosion is poorly understood. We want to increase the number of explosive transients whose progenitor systems have been directly identified in order to better understand the diversity of explosive transients. This is only possible when progenitor stars are resolved in deep, high-resolution pre-explosion imaging, but such cases are rare. The goal of our program will be to leverage such cases by triggering a target opportunity program to obtain precise relative astrometry between pre-explosion and Gemini adaptive optics imaging. These data will constrain the progenitor system location, revealing which source produced the explosion. With the growing sample of progenitor system detections, we will investigate trends in the entire population.
