Abstract

We present results from the Hubble Higher z Supernova Search, the first space-based open field survey for Supernovae (SNe). In cooperation with die Great Observatories Origins Deep Survey, we have used the Hubble Space Telescope with the Advanced Camera for Surveys to cover ∼300 arcmin 2 in the area of the Chandra Deep Field South and the Hubble Deep Field North on five separate search epochs (separated by ∼45 day intervals) to a limiting magnitude of F850LP ≈ 26. These deep observations have allowed us to discover 42 SNe in the redshift range 0.2 < z < 1.6. As these data span a large range in redshift, they are ideal for testing the validity of Type la supernova progenitor models with the distribution of expected "delay times," from progenitor star formation to Type Ia SN explosion, and the SN rates these models predict. Through a Bayesian maximum likelihood test, we determine which delay-time models best reproduce the redshift distribution of SNe la discovered in this survey. We find that models that require a large fraction of "prompt" (less than 2 Gyr) SNe la poorly reproduce the observed redshift distribution and are rejected at greater man 95% confidence. We find that Gaussian models best fit the observed data for mean delay times in the range of 2-4 Gyr.
