Abstract

We present measurements of the Type Ia supernova rate in both high-redshift galaxy clusters and the field. For the first time, we detect a significant increase in the cluster rate with redshift, when compared to lower-redshift measurements. Our field rate measurement indicates an SN Ia rate that is flat or decreasing with redshift at z > 1, in general agreement with previous studies. These are results from the Hubble Space Telescope Cluster Supernova Survey (PI Perlmutter; see Dawson et al. 2009), in which we discovered a total of 20 SNe Ia, including the first nine SNe Ia ever discovered in z > 0.9 clusters, and eight z > 0.9 SNe Ia in the field. SN Ia rate meaurements provide one of the few available probes of the as-yet-unknown SN Ia progenitor system. The cluster rate provides a direct measure of the SN Ia delay time distribution, which can be used to differentiate between progenitor scenarios. Additionally, the cluster rate is a key factor for studies of the metallicity enrichment of the intracluster medium, and can even be used to constrain the population of intracluster stars. With our result, the cluster rate measurements alone constrain the SN Ia rate to decline with delay time as t ^{-1.3 ± 0.9} and have already been combined with other measurements to yield tighter constraints (e.g., Maoz et al. 2010). Measurements of the high-redshift volumetric SN Ia rate test specific progenitor scenarios predicting a metallicity dependence of the SN Ia rate, and are an important input in designing future high-redshift SN programs. This work has been supported by the Office of Science, U.S. Department of Energy, through contract DE-AC02-05CH11231 and in part by NASA through grants associated with HST-GO-10496.
