Description
In this talk, we present our recently performed 3D fully relativistic long term simulations (Tpb~300-400ms) of gravitational collapse of massive progenitor stars with adopting several modern EoSs of Hempel et al.'12 and of Steiner et al.'13. Through these multiple EoSs and progenitor models, we found more massive progenitor star and softer equation of state lead to more vigorous SASI activity which imprints its characteristic signatures in both gravitational waves (GWs) and neutrino signals. To discuss the possibility of deciphering post bounce hydrodynamic evolution imprinted in GWs, we did our newly developed coherent network analysis and estimated such as the detection limit. We also investigated whether the coherency is found between (1) modulations of GW signals which are associated with SASI activity and of evaluated neutrino count rate; (2) directions of SASI sloshing motion and of prominent neutrino propagation. From these, we can suggest the importance of future coherent observational system between GW and neutrino detectors.
