Cosmology with the SDSS II Supernova Survey
Craig Wheeler ~ UT Austin

abstract
The Sloan Digital Sky Survey-II (SDSS-II) did a three-year survey to identify and measure
light curves for intermediate-redshift (0.05 < z < 0.35) Type Ia supernovae (SNe Ia) using
repeated five-band (ugriz) imaging over an area of 300 sq. deg. The survey region was a
stripe 2.5 degrees wide centered on the celestial equator in the Southern Galactic Cap
for which there were deep reference images for discovery of new objects. The HET played
an important role in providing spectra for identifications. Results for measurements of
the Hubble diagram for 103 Type Ia supernovae (SNe) with redshifts 0.04 < z < 0.42,
discovered during the first season (Fall 2005) will be summarized. These data fill in the
redshift "desert" between low- and high-redshift SN Ia surveys. The SDSS-II measurements
are combined with other SN data, measurements of Baryon Acoustic Oscillations, and with
CMB temperature anisotropy measurements from WMAP to give an estimate of the cosmological
parameters w and Omega_M, assuming a spatially flat cosmological model with constant
dark energy equation of state parameter, w. For the combined sample of 288 SNe Ia, we
find w = -0.76 +/- 0.07(stat) +/- 0.11(syst), Omega_M = 0.306 +/- 0.019(stat) +/- 0.023(syst)
using the MLCS2k2 light curve fitter and w = -0.96 +/- 0.06(stat) +/- 0.12(syst),
Omega_M = 0.265 +/- 0.016(stat) +/- 0.025(syst) using the SALT-II fitter. The discrepancy
between these results was traced to a difference in the rest-frame UV model combined with
a different luminosity correction from color variations; these differences mostly affect
the distance estimates for the SNLS and HST supernovae. |
