The Progenitors of Type Ia Supernovae
Christopher J. Pritchet, D. Andrew Howell, Mark Sullivan
Type Ia supernovae (SNe Ia) occur in both old, passive galaxies and active, star-forming galaxies. This fact, coupled with the strong dependence of SN Ia rate on star formation rat…
SiFTO: An Empirical Method for Fitting SNe Ia Light Curves
A. Conley, M. Sullivan, E. Y. Hsiao +14
We present SiFTO, a new empirical method for modeling type Ia supernovae (SNe Ia) light curves by manipulating a spectral template. We make use of high-redshift SN observations whe…
The Supernova Type Ia Rate Evolution with SNLS
J. D. Neill, M. Sullivan, D. Balam +36
We present a progress report on a project to derive the evolution of the volumetric supernova Type Ia rate from the Supernova Legacy Survey. Our preliminary estimate of the rate ev…
Gemini Spectroscopy of Supernovae from SNLS: Improving High Redshift SN Selection and Classification
D. A. Howell, M. Sullivan, K. Perrett +22
We present new techiques for improving the efficiency of supernova (SN) classification at high redshift using 64 candidates observed at Gemini North and South during the first year…
