Abstract:

Core-Collapse Supernovae are a fantastic laboratory to study fundamental physics.  The messengers from the core--neutrinos and gravitational waves--carry a wealth of information about the dynamics, thermodynamics, underlying physics, and structure of massive stars at the end of their lives.  I will start this talk with a review of the theory and status of core-collapse supernova simulations and then go on to discuss some of the ways we can use multimessenger signals from supernovae to probe the extreme physics.  From quark-hadron phase transitions emitting unique gravitational wave and neutrino signals to neutrino echos following black hole formation revealing properties of the progenitor star and neutrinos tellings us precise information about the distance to and progenitor mass (!) of galactic supernovae, even before the optical signal is emitted.  If time permits, I will also talk about current efforts to model the population of core-collapse supernovae using parameterized 1D models.
