AN INTENSIVE<i>HUBBLE SPACE TELESCOPE</i>SURVEY FOR<i>z</i>&gt;1 TYPE Ia SUPERNOVAE BY TARGETING GALAXY CLUSTERS

We present a new survey strategy to discover and study high-redshift Type Ia supernovae (SNe Ia) using the Hubble Space Telescope (HST). By targeting massive galaxy clusters at 0.9 < z < 1.5, we obtain a twofold improvement in the efficiency of finding SNe compared to an HST field survey …
