Description
Core-collapse supernovae stand out as key multi-messenger candidates to probe the internal dynamics of stellar supernova explosions with gravitational waves, light, and neutrinos. These complex processes have motivated multiple efforts to simulate core-collapse supernovae and predict the observational signatures with different simulation and progenitor parameters. In order to develop a relevant gravitational-wave search, we have characterized waveform morphologies derived from simulations to outline effective patterns. Our gravitational-wave search for core-collapse supernovae, Omicron-x, is based on the cross-correlation of Q-transform spectrograms and is essentially un-modelled, allowing us to scan a large parameter space. Building on our waveform studies, we measure the search sensitivity to various components in supernova gravitational-wave signals.
