Photometric Calibration of the Supernova Legacy Survey Fields
N. Regnault
The 5-year project Supernova Legacy Survey (SNLS) delivers Type-Ia supernovae (SNe Ia) per year, in the redshift range , with well-sampled ligh…
DUNE: The Dark Universe Explorer
A. Refregier, O. Boulade, Y. Mellier +22
Understanding the nature of Dark Matter and Dark Energy is one of the most pressing issues in cosmology and fundamental physics. The purpose of the DUNE (Dark UNiverse Explorer) mi…
The Rise Time of Type Ia Supernovae from the Supernova Legacy Survey
A. Conley, D. A. Howell, A. Howes +24
We compare the rise times of nearby and distant Type Ia supernovae (SNe Ia) as a test for evolution using 73 high-redshift spectroscopically-confirmed SNe Ia from the first two yea…
Rates and properties of type Ia supernovae as a function of mass and star-formation in their host galaxies
M. Sullivan, D. Le Borgne, C. J. Pritchet +27
(ABRIDGED) We show that Type Ia supernovae (SNe Ia) are formed within both very young and old stellar populations, with observed rates that depend on the stellar mass and mean star…
The Type Ia Supernova Rate at z ~0.5 from the Supernova Legacy Survey
J. D. Neill, M. Sullivan, D. Balam +33
We present a measurement of the distant Type Ia supernova rate derived from the first two years of the Canada -- France -- Hawaii Telescope Supernova Legacy Survey. We observed fou…
Towards a Cosmological Hubble Diagram for Type II-P Supernovae
Peter Nugent, Mark Sullivan, Richard Ellis +13
We present the first high-redshift Hubble diagram for Type II-P supernovae (SNe II-P) based upon five events at redshift up to z~0.3. This diagram was constructed using photometry…
