The Sloan Digital Sky Survey-II Supernova Survey: Technical Summary

Joshua A. Frieman, B. Bassett, A. Becker +98

The Sloan Digital Sky Survey-II (SDSS-II) has embarked on a multi-year project to identify and measure light curves for intermediate-redshift (0.05 < z < 0.35) Type Ia supernovae (…

The distant Type Ia supernova rate

R. Pain, S. Fabbro, M. Sullivan +26

We present a measurement of the rate of distant Type Ia supernovae derived using 4 large subsets of data from the Supernova Cosmology Project. Within this fiducial sample, which su…

Measuring the properties of extragalactic dust and implications for the Hubble diagram

Ariel Goobar, Lars Bergstrom, Edvard Mortsell

Scattering and absorption of light by a homogeneous distribution of intergalactic large dust grains has been proposed as an alternative, non-cosmological explanation for the faintn…
