Description
Core-Collapse Supernovae (CCSNe) are the spectacular and violent deaths of massive stars. The study of Gravitational Waves (GW) from CCSNe can help elucidate the explosion mechanism and give us information about the physical properties of the collapsed core like Equation of State, neutrino mass hierarchy or unknown physics. In this talk I will review the state-of-art techniques used to search for GW from CCSNe and current work on detection perspectives with future GW Observatories. Their detection requires a deep understanding of multi-dimensional CCSN simulations, data analysis caveats, detector response, as well as the insights provided by neutrino and electromagnetic messengers. I will talk about properties of the CCSN waveforms, algorithm development that uses the deterministic features (like g-modes) used to increase the visible distance for CCSN detection. I will also review the detection range, future algorithm developments and detection capabilities with the designs of future detector configurations.
