Title: Superluminous Supernovae in the Epoch of Reionization

Abstract: Our proposal capitalizes on the high red sensitivity and large field of view of DECam to detect the most luminous and rarest supernovae near the epoch of reionization. With deep reference fields in hand, we will execute with a cadence and depth that will enable the detection of super- luminous supernovae (SLSNe) at z $sim$ 6 - 7. SLSNe are a recently observed class of supernovae that are 10-100x more luminous than typical supernovae. This class includes pair-instability supernovae that are a third type of supernova explosion in which only 3 candidate events are currently known, but have a high expected density at high redshift. It is crucial to obtain data on more of these SLSN events at these epochs, since even their basic underlying physics (eg, magnetars vs black holes) is not currently well constrained, and any additional events would be very valuable. These observations will greatly extend the current reach of supernovae research at high redshifts, examining their occurrence rate and properties, and determining their contribution to cosmic reionization.
