Abstract:
The Carnegie Supernova Project (CSP) is a five-year survey being
carried out at the Las Campanas Observatory to obtain high-quality
light curves of ∼100 low-redshift Type Ia supernovae (SNe Ia) in a
well-defined photometric system. Here we present the first release of
photometric data that contains the optical light curves of 35 SNe Ia,
and near-infrared light curves for a subset of 25 events. The data
comprise 5559 optical (ugriBV) and 1043 near-infrared (Y JHKs) data
points in the natural system of the Swope telescope. Twenty-eight SNe
have pre-maximum data, and for 15 of these, the observations begin at
least 5 days before B maximum. This is one of the most accurate data
sets of low-redshift SNe Ia published to date. When completed, the CSP
data set will constitute a fundamental reference for precise
determinations of cosmological parameters, and serve as a rich
resource for comparison with models of SNe Ia.
Description:
Our follow-up program focuses on SNe discovered by professional and
amateur astronomers who report them to the IAU Circulars (IAUC), the
IAU Electronic Telegrams (CBET), or occasionally, directly to us via
electronic mail. When word arrives of a new candidate, we place it in
our follow-up queue. Photometric monitoring is obtained entirely at
the Las Campanas Observatory (LCO).
