Early Results from the SDSS-II Supernova Survey
Abstract
The Sloan Digital Sky Survey II is currently conducting a supernova (SNe) search, where approximately 300 square degrees of the sky are scheduled for multi-band imaging on a cadence of two days with the primary goal of studying type Ia SNe as cosmological distance indicators. The first of the three-year program began in early September and will continue until the end of November 2005. During the first month, the survey has discovered and obtained multi-band light curves and spectroscopic data of 50 SN Ia from z = 0.05 - 0.4, a redshift "desert" that is poorly sampled in other local and high-redshift searches. We present some early results from the first year of the survey and discuss future prospects.
