Title: Host-Galaxy Environments of the Universe's Most Extreme Explosions Across Cosmic History
Description: The catastrophic explosions of stars as supernovae and gamma-ray bursts provide a window into some of the most extreme physics that occurs in our universe - the formation of black holes, the orbital decay and eventual merger of compact binaries due to gravitational radiation, and ultra-relativistic shocks and outflows produced in these processes. Moreover, because it is possible to study these events at great distances when the Universe was a fraction of its current age, these events may be extremely useful as astronomical probes of cosmic history - but only if we can understand the ingredients necessary to produce these explosions in the first place. I will discuss two large surveys I and my collaborators are leading to study the connection between extreme transients and their galaxy environments, using a variety of telescope facilities on the ground and in orbit. Each class of transient appears to form in different environments - suggesting that the specific influences leading to each type of explosion are distinct. In spite of this complexity, we find that metallicity appears to be the dominant factor in determining whether extreme events like GRBs and luminous supernovae can form - a conclusion that is encouraging for the use of these events as probes of the early universe.
