Abstract:
In the course of the Sloan Digital Sky Survey (SDSS-I), a large
fraction of the surveyed area was observed more than once due to field
tiling overlap, usually at different epochs. We utilize some of these
data to perform a supernova (SN) survey at a mean redshift of z=0.2.
Our archival search, in 5 per cent of the SDSS-I overlap area,
produces 29 SN candidates clearly associated with host galaxies. Using
the Bayesian photometric classification algorithm of Poznanski et al.
(2002PASP..114..833P), and correcting for classification bias, we find
17 of the 29 candidates are likely Type Ia SNe.
