HST Cluster Supernova Survey. VI. SNIa rate
Listed in IVOA Registry (Virtual Observatory)
We present a measurement of the volumetric Type Ia supernova (SN Ia) rate out to z=~1.6 from the Hubble Space Telescope Cluster Supernova Survey.
Description
In observations spanning 189 orbits with the Advanced Camera for Surveys we discovered 29 SNe, of which approximately 20 are SNe Ia. Twelve of these SNe Ia are located in the foregrounds and backgrounds of the clusters targeted in the survey.
Using these new data, we derive the volumetric SN Ia rate in four broad redshift bins, finding results consistent with previous measurements at z>~1 and strengthening the case for an SN Ia rate that is >~0.6x10^-4^h^3^_70_/yr/Mpc3 at z~1 and flattening out at higher redshift. We provide SN candidates and efficiency calculations in a form that makes it easy to rebin and combine these results with other measurements for increased statistics.

Finally, we compare the assumptions about host-galaxy dust extinction used in different high-redshift rate measurements, finding that different assumptions may induce significant systematic differences between measurements.
