# The gravitational wave signal from core-collapse supernovae

@article{Morozova2018TheGW, title={The gravitational wave signal from core-collapse supernovae}, author={V. Morozova and D. Radice and A. Burrows and D. Vartanyan}, journal={arXiv: High Energy Astrophysical Phenomena}, year={2018} }

We study gravitational waves (GWs) from a set of two-dimensional multi-group neutrino radiation hydrodynamic simulations of core-collapse supernovae (CCSNe). Our goal is to systematize the current knowledge about the post-bounce CCSN GW signal and recognize the templatable features that could be used by the ground-based laser interferometers. We demonstrate that starting from ~400ms after core bounce the dominant GW signal represents the fundamental quadrupole (l=2) oscillation mode (f-mode) of… Expand
