Abstract

Since 2008 our collaboration has pioneered the use of Laser Guide Star Adaptive Optics to probe the previously-hidden population of core-collapse supernovae within Luminous Infrared Galaxies (LIRGs). We are extending our survey to the southern LIRGs to exploit the significant improvement in PSF uniformity and field of view offered by GSAOI with GeMS. In April 2013 we detected a new supernova less than 200 pc from the nucleus of the LIRG IRAS 18293-3413. Now that the supernova will have faded away we request a small allocation of time to re-image the host galaxy so that we can reliably subtract its contribution to the supernova's brightness at earlier epochs. This will finally enable both the supernova's type and (from its colours) the line-of-sight extinction to be determined.
