Dark energy constraints and correlations with systematics from CFHTLS weak lensing, SNLS supernovae Ia and WMAP5
M. Kilbinger, K. Benabed, J. Guy +15
We combine measurements of weak gravitational lensing from the CFHTLS-Wide survey, supernovae Ia from CFHT SNLS and CMB anisotropies from WMAP5 to obtain joint constraints on cosmo…
The effect of progenitor age and metallicity on luminosity and 56Ni yield in Type Ia supernovae
D. A. Howell, M. Sullivan, E. F. Brown +23
Timmes, Brown & Truran found that metallicity variations could theoretically account for a 25% variation in the mass of 56Ni synthesized in Type Ia supernovae (SNe Ia), and thus ac…
PHotometry Assisted Spectral Extraction (PHASE) and identification of SNLS supernovae
S. Baumont, C. Balland, P. Astier +7
Aim: We present new extraction and identification techniques for supernova (SN) spectra developed within the Supernova Legacy Survey (SNLS) collaboration. Method: The new spectral…
Clustering of supernova Ia host galaxies
R. G. Carlberg, M. Sullivan, D. Le Borgne +16
For the first time the cross-correlation between type Ia supernova host galaxies and surrounding field galaxies is measured using the Supernova Legacy Survey sample. Over the z=0.2…
Improved Cosmological Constraints from New, Old and Combined Supernova Datasets
M. Kowalski, D. Rubin, G. Aldering +67
We present a new compilation of Type Ia supernovae (SNe Ia), a new dataset of low-redshift nearby-Hubble-flow SNe and new analysis procedures to work with these heterogeneous compi…
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…
