Title: Superluminous Supernovae in the Epoch of Reionization
Abstract: Our program 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 imaging data in hand on our three DECam deep fields, we are now detecting transients at 25th magnitude which are candidate super-luminous supernovae (SLSNe) at z $sim$ 6-7. SLSNe are a class of supernovae 10-100x more luminous than typical supernovae, and include pair-instability supernovae for which only a few moderate-redshift candidate events are currently known, but have a high expected density at high redshift. It is crucial to obtain data on more such SLSN events at these epochs, since even their basic underlying physics is not currently well constrained (eg, magnetars vs black holes). A key observational aspect of our program for 2017B is to follow the light curve of the brightest known current epoch SLSN candidate, which we discovered in our 2016B DECam run (luminosity of 2e11 Lsun at z $sim$ 6). 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.
