Quantifying Rotational Effects on Neutrino Emission in Core-collapse Supernovae

Neutrino and gravitational wave (GW) emission from the next nearby core collapse supernova (CCSN) will be important multimessengers, containing intrinsic properties of the CCSN and its progenitor star. Prior work has related expressions for the earlier GW "core-bounce" signal and later dominant frequency mode from the protoneutron star (PNS) to CCSN parameters like the rotation and density profile. Other work has shown similar relationships, including CCSN neutrino luminosities and mean energies. We analyze a set of >100 2D neutrino radiation-hydrodynamic CCSN simulations to more precisely quantify relationships between neutrinos, GW observables, and CCSN properties: angular momentum and compactness. We propose a new multimessenger-based method to provide a constraint on distance. We also quantify viewing angle dependence of neutrino detectabiliity in rotating CCSNe.
