Abstract:
We present photometric and spectroscopic observations of 23
high-redshift supernovae (SNe) spanning a range of z=0.34-1.03, nine
of which are unambiguously classified as Type Ia. These SNe were
discovered during the IfA Deep Survey, which began in 2001 September
and observed a total of 2.5deg2 to a depth of approximately m∼25-26
in RIZ over 9-17 visits, typically every 1-3 weeks for nearly 5
months, with additional observations continuing until 2002 April.
Description:
SNe were identified by matching spectral features with those of SNe Ia
through a program called SNID (J.L. Tonry 2004, in preparation),
which cross-correlates an observed spectrum against a set of template
spectra to determine the SN type, redshift, and age.
