Multi-Messenger Diagnostics of the Supernova Engine*

Core-collapse supernovae play important roles in a wide range of astrophysics including transient outbursts that probe stellar evolution, the formation of compact remnants and the production and injection of heavy elements into the galaxy. Understanding these roles requires an understanding of the supernova engine. In this talk, I will review the current status of the theories behind supernova explosions and the observational constraints (both past and future) that can be used to confirm these engines and probe the extreme physics behind them. A broad range of observations exist from direct (but difficult to obtain) probes to indirect probes for which we can obtain much more data. We will discuss these different probes and the physics modeling required to apply them to our understanding of the physics behind the supernova engine.
