The Type Ia Supernova Rate at z ~ 0.4
R. Pain, I. Hook, S. Perlmutter +23
We present the first measurement of the rate of Type Ia supernovae at high redshift. The result is derived using a large subset of data from the Supernova Cosmology Project as desc…
Observation of Cosmological Time Dilation using Type Ia Supernovae as Clocks
G. Goldhaber, S. Deustua, S. Gabi +23
This work is based on the first results from a systematic search for high redshift Type Ia supernovae. Using filters in the R-band we discovered seven such SNe, with redshift z = 0…
K Corrections For Type Ia Supernovae and a Test for Spatial Variation of the Hubble Constant
A. Kim, S. Deustua, S. Gabi +23
Cross-filter K corrections for a sample of "normal" Type Ia supernovae (SNe) have been calculated for a range of epochs. With appropriate filter choices, the combined statistical a…
Scheduled Discoveries of 7+ High-Redshift Supernovae: First Cosmology Results and Bounds on q_0
S. Perlmutter, S. Deustua, S. Gabi +23
Our search for high-redshift Type Ia supernovae discovered, in its first years, a sample of seven supernovae. Using a "batch" search strategy, almost all were discovered before max…
