3D Core-Collapse Supernova Models: Gravitational and Neutrino Signatures

Core-Collapse Supernovae (CCSN) are among the most promising sources for multi-messenger astronomy since they produce strong electromagnetic and neutrino signals, as well as powerful gravitational wave (GW) bursts. Our group has developed the CHIMERA code specifically to simulate CCSN in 1, 2, and 3 spatial dimensions, incorporating hydrodynamics, neutrino transport and thermonuclear kinetics. We present here first-principle 2D and 3D CCSN models covering, in the case of the 2D models, the first second after post-bounce. The 2D runs were based on 12, 15, 20 and 25M progenitors, with all developing full-blown explosions with energies up to 1 Bethe. The computationally expensive 3D run evolves a 15M progenitor and is currently undergoing. We provide an extensive analysis of the GW and neutrino signals obtained in those runs and study their detectability by Earth-based observatories.
