Multimessengers from 3D Core-Collapse Supernovae

TL;DR

This paper presents the first 3D simulation of core-collapse supernovae, analyzing gravitational wave and neutrino signals to understand supernova dynamics and the supernova engine.

Contribution

It provides the first detailed 3D simulation of neutrino and gravitational wave signals from a non-rotating supernova progenitor.

Findings

Neutrino and GW signals exhibit distinct phases of supernova evolution.

Hydrodynamic instabilities significantly influence the GW and neutrino signatures.

Abstract

We present gravitational wave and neutrino signatures obtained in our first principle 3D core-collapse supernova simulation of 15M non-rotating progenitor with Chimera code. Observations of neutrinos emitted by the forming neutron star, and gravitational waves, which are produced by hydrodynamic instabilities is the only way to get direct information about the supernova engine. Both GW and neutrino signals show different phases of supernova evolution.
