Abstract
Supernovae are known to astronomers for more than a thousand years, but their gravitational waves have never been detected, even though they're expected to carry a great wealth of information which could not be obtained in any other way. Our research was about improving the existing search for Gravitational waves from Core collapse supernovae with laser interferometers. In particular it was about two areas of supernova research : characterizing and improving the existing method to narrow down the interval of time where the team searches for such waves, and comparing the previously used quartic fit routine to a physical model to see which estimation of the time of the shockwave breakout was more effective at narrowing down the window to find the time of the gravitational wave emission. More explicitly, to improve gravitational wave detection, an estimate of the time of the core collapse can be made, which is the same time gravitational waves are emitted, from the electromagnetic emission. This estimate has uncertainties and and as consequence it only produces a time interval where it can be searched for GWs associated with a specific Supernova. The goal of this research was to publish a paper on both areas of research mentioned, and while no papers have yet to be published, our findings have brought more insight to the nature of Core collapse supernovae and the gravitational waves they emit.
