The Hubble Space Telescope Cluster Supernova Survey: An Intensive HST Survey for z>1 Type Ia Supernovae by Targeting Galaxy Clusters
Survey Paper: Dawson et al. (The Supernova Cosmology Project) 2009, AJ, 138, 1271 [ADS] [arXiv] 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 and a factor of three improvement in the total yield of SN detections in relatively dust-free red-sequence galaxies. In total, sixteen SNe were discovered at z > 0.95, nine of which were in galaxy clusters. This strategy provides a SN sample that can be used to decouple the effects of host galaxy extinction and intrinsic color in high redshift SNe, thereby reducing one of the largest systematic uncertainties in SN cosmology.

SN Light Curves	Survey Statistics
SN lightcurves and z850 AB magnitudes of the high redshift SNe discovered in the survey. Each lightcurve is labeled with the SN redshift in the same color. NICMOS and i775 observations are not shown, nor are additional SNe at z<0.8.	The redshift distribution of the SNe discovered in our ACS program. The upper panel shows the distribution of red-sequence galaxies that had SNe Ia, with the cluster members indicated by ``C''. The asterisk indicates [OII] emission in the spectrum of a galaxy with red-sequence color and spectral features as explained in the text. The lower panel shows the distribution for the other SN hosts. For z > 0.95, the number of SNe in cluster galaxies (9) is comparable to the number of SNe in field galaxies (7).
