Abstract:
This paper describes the data release of the Sloan Digital Sky
Survey-II (SDSS-II) Supernova Survey conducted between 2005 and 2007.
Light curves, spectra, classifications, and ancillary data are
presented for 10,258 variable and transient sources discovered through
repeat ugriz imaging of SDSS Stripe 82, a 300deg2 area along the
celestial equator. This data release is comprised of all transient
sources brighter than r~=22.5mag with no history of variability prior
to 2004. Dedicated spectroscopic observations were performed on a
subset of 889 transients, as well as spectra for thousands of
transient host galaxies using the SDSS-III BOSS spectrographs.
Photometric classifications are provided for the candidates with good
multi-color light curves that were not observed spectroscopically.
From these observations, 4607 transients are either spectroscopically
confirmed, or likely to be, supernovae, making this the largest sample
of supernova candidates ever compiled. We present a new method for SN
host-galaxy identification and derive host-galaxy properties including
stellar masses, star-formation rates, and the average stellar
population ages from our SDSS multi-band photometry. We derive SALT2
distance moduli for a total of 1443 SN Ia with spectroscopic redshifts
as well as photometric redshifts for a further 677 purely-photometric
SN Ia candidates. Using the spectroscopically confirmed subset of the
three-year SDSS-II SN Ia sample and assuming a flat {LAMBDA}CDM
cosmology, we determine {OMETA}M=0.315±0.093 (statistical error
only) and detect a non-zero cosmological constant at 5.7σ.
Description:
The SDSS-II SN data were obtained during three-month campaigns in the
Fall of 2005, 2006, and 2007 as part of the extension of the original
SDSS.
