Detecting gravitational waves from core-collapse supernovae

Advanced LIGO and Virgo have detected gravitational waves from compact merging binaries such as black holes and neutron stars. The next discovery could be associated with other astrophysical sources. Core-collapse supernova is one of the most promising candidates and multi-messenger sources. It can be detected electromagnetically, as well as via gravitational waves and neutrinos. Detecting gravitational waves from core-collapse supernovae will allow for direct investigations of the engine driving explosion's dynamics. This talk will give an overview of the gravitational waves from core-collapse supernovae and the search method, with a focus on the search results from the recent supernova candidate. Otherwise, this talk will show the constraints on the properties of the supernova engine, including the upper limits on the gravitational wave emission energy and power.
