Title: Redshifts and Host Galaxy Spectra for the Completed Pan-STARRS Supernova Survey

Abstract: By the fall of 2014, the Pan-STARRS (PS1) transient survey will be complete. We propose to use the AAT to measure redshifts of the host galaxies of transients detected in the southernmost PS1 medium deep (MD) field. We will combine these data with redshifts from our ongoing MMT Hectospec survey of the northern PS1 MD fields. With these redshifts we will be able to to build the world's largest sample of cosmologically- useful Type Ia supernovae (SN Ia) to reduce the uncertainty on the dark energy equation of state. With such a large sample, we will be able to measure cosmological parameters with higher accuracy by primarily using SN Ia in spectroscopically- and morphologically-confirmed early-type hosts, as these SN are better distance indicators. We will simultaneously observe hundreds of core-collapse SN host galaxies and AGN, allowing us to study the progenitors of CC SN and to identify tidal disruption events, superluminous SN, and other rare events in PS1 that can only be found by using redshifts to establish their rest-frame durations and luminosities.
