Title: SUDSS: Survey Using Decam for Superluminous Supernovae

Abstract: We propose to continue SUDSS, our innovative search for superluminous supernovae (SLSNe): a new class of astrophysical transient with absolute magnitudes in the range -21 to -23, some 50 times brighter than normal supernova types, which we will detect out to z$~3. Our survey significantly increases both the quantity and quality of SLSN observations. In concert with our planned spectroscopic follow-up campaign, the SUDSS sample will allow us to probe theories of the origin of SLSNe, and test new empirical relations that enable these events to be used as distance indicators in the z$>1 universe. Ongoing transient searches in their current design are unable to detect many SLSN events (e.g., <15 expected in DES) due to their rarity and long duration light-curves (hundreds of days observer-frame). SUDSS is predicted to find 200 well-observed SLSNe over 3 years by imaging 24deg^2 in griz to a magnitude limit of i_AB~eq25 every 14 days. This dataset will be unique and promote significant additional science in these well-observed legacy fields.
