Detail for Program: GN-2010A-Q-40

Abstract

We wish to complete our Laser Guide Star Adaptive Optics (LGSAO) program commenced in Semester 2008A to detect and study supernovae (SNe) in the nuclear regions of a sample of northern Luminous Infrared Galaxies (LIRGs). Discovering this previously hidden population of highly-obscured core-collapse supernovae is crucial for revising the optically-derived SN rates (which certainly miss a significant fraction of all the SN events in the local and distant Universe), which in turn provide an independent measurement of the star formation history of the Universe. This program has already discovered 2 otherwise unnoticed supernovae including SN 2008cs, which is not only the first supernova ever discovered using LGSAO techniques, but also the most heavily-extinguished supernova yet known, with A_V~18 mag.
