The SDSS-II Supernova Survey is a proposed optical survey to discover supernovae in the redshift range 0.05 < z < 0.35, and to measure their lightcurves for use as a probe of dark energy. The poster will present preliminary results of a test campaign in the Fall of 2004, as well as a proposal for a three-year run in 2005-2007.
A feasibility study in September-November of 2004 used the 2.5 m SDSS telescope at APO to repeat-scan 140 sq. degrees every other night. These scans were used to discover SN and to measure their lightcurves. A reduction pipeline running at APO was used to find SN candidates (g and r bands only) within 2 days; spectra for these candidates were taken by the ARC 3.5 m and HET telescopes. This test run resulted in 16 spectroscopically confirmed SN Ia, 5 type II and one type Ic.
The SDSS-II proposal is a three-year program to measure 200 SN Ia lightcurves in the five SDSS bands (ugriz). Compared to the 2004 test run, we anticipate lightcurve yield improvements as follows: > 2 from longer campaigns, x2 from increased sky coverage (along with scanning every night instead of every other night), and better detection efficiency from improved software. In addition to using the ARC 3.5 and HET telescopes for spectroscopy, proposals are pending to use the Subaru 8m, WHT 4.2m, NTT 3.5m, VLT 10m, and the Calar Alto 3.5m.
Funding for the Sloan Digital Sky Survey (SDSS) has been provided by the Alfred P. Sloan Foundation, the Participating Institutions, the National Aeronautics and Space Administration, the National Science Foundation, the U.S. Department of Energy, the Japanese Monbukagakusho, and the Max Planck Society.
