Abstract: The detection of neutrinos and gravitational waves from the next galactic core-collapse supernova (CCSN) has become almost a certainty. In order to properly interpret these detections, a thorough understanding of the landscape of possible CCSN events, and their multi-messenger signals, is needed. I will present recent progress toward understanding the information embedded in multi-messenger signals from CCSNe, and how we can extract it. The neutrino and gravitational wave signals are strongly correlated with properties of the progenitor star, dynamics of the system, and remnant compact object. Additionally, these signals will provide unique constraints on fundamental physics, such as the nuclear equation of state and neutrino flavor mixing.
