Steering Astronomy Toward Gravitational Wave-Supernova Science

ORAL

Abstract

\par Core-Collapse supernovas (CCSNe) mark the dynamic and explosive end of the lives of massive stars by emitting the gravitational wave that is detectable by detectors such as the Laser Interferometer Gravitational-Wave Observatory (LIGO). LIGO has been one of the first collaborations to create ways to collect and analyze data that would distinguish the gravitational waves from background noise produced on Earth. Optical observations of supernovas in the Local Universe provide trigger times (with a typical uncertainty of a few days) and precise sky locations, while an electromagnetic observation would provide a core-collapse trigger time (with an uncertainty of a few seconds) and a sky location. We describe a method that takes into account optical and electromagnetic observational techniques for detection of CCSNe within the Local Universe, which encompasses a volume of 20 Mpc. Providing distance sensitivity estimates for the rate of CCSNe within the Local Field and the Virgo Cluster specializes the implementation of the CCSNe rate toward specifically gravitational wave detection.
