Title: Host Galaxy Images for High Redshift Supernovae

Abstract: Type Ia supernovae provide the most direct evidence for an accelerating universe. Continuing studies of supernovae will allow us to improve these measurements, reduce systematic errors, and begin to address the physical nature of the ``dark energy'' driving the acceleration. To be placed on the Hubble diagram, supernovae require measurements of the peak flux, color, and decay rate of their lightcurves. These measurements in turn require supernova-free host galaxy images. In order to complete our extensive 2002 supernova campaign, which involved coordinated observations with the CTIO 4m, WIYN, Gemini North, ACS on HST, and other telescopes, this proposal requests time to obtain host galaxy images in R and I with WIYN/MIMO for six SNe at z<0.6 and with Gemini-N/NIRI for two SNe at z=1.1. In addition, these images will further our studies of the dependence of supernova properties and extinctions on host galaxy morphologies and luminosities.
