Title: The Next Frontier: High-Redshift Supernovae in the HST Frontier Fields

Abstract: The \it Hubble Space Telescope is about to start a major survey program to observe six Frontier Fields (FFs). Like previous \it HST surveys (e.g., GOODS, CANDELS, CLASH), these data will be used to discover high-redshift supernovae (SNe). However, the FF survey is unique: half of the fields are centered on strong-lensing clusters, and each epoch will reach \about 4\times deeper than previous surveys did. These advantages will allow us to discover SNe at unprecedented redshifts and to build up a small but powerful sample of lensed Type Ia SNe (\SNIa). With the high-z sample, we will for the first time measure the \SNIa rate at z > 2, providing a sensitive test of \SNIa\ progenitor models. In addition, \about 10 lensed \SNIa at z > 0.5 will each deliver an extremely precise single-point probe through the lensing cluster - a unique test of the mass models for FF clusters. We have an approved 60-orbit \it HST program that will supplement FF imaging to improve SN light-curve coverage. Gemini spectroscopy of the brightest SNe will provide critical redshifts and classifications for the bulk of the SN sample (at z \lesssim 1.3), adding significant value to our approved \it HST program. The Gemini sample will include most of the lensed \SNIa, and will be an important anchor for the highest-redshift rates, connecting this new frontier to the well-studied low-z regime.
