LIGO Seminar

The next galactic core-collapse supernova (CCSN) has already exploded, and its electromagnetic (EM) waves, neutrinos, and gravitational waves (GWs) may arrive at any moment. We present an extensive study in the potential sensitivity of prospective detection scenarios for GWs from CCSN sources in the neighborhood of the Local Group of galaxies, in addition to more distance sources in galaxies with substantial CCSN rates. In the first study of its kind, we make statements on the detectability of astrophysically-motivated signals (including waveforms from state-of-the-art 3D CCSN simulations), in addition to the broadband sensitivity of the Advanced detectors to sine-Gaussian bursts. Using real GW detector data, recolored to the predicted power spectral densities of the Advanced LIGO and Advanced Virgo detectors, and considering various on-source regions to investigate the improvement in sensitivity to GW searches for CCSNe by the presence of coincident neutrino and EM triggers, we demonstrate the first quantitative predictions on the detectability of GWs from CCSNe during the Advanced detector era.
