Subluminous Type Ia Supernovae at High Redshift from the Supernova Legacy Survey
S. Gonzalez-Gaitan, K. Perrett, M. Sullivan +15
The rate evolution of subluminous Type Ia Supernovae is presented using data from the Supernova Legacy Survey. This sub-sample represents the faint and rapidly-declining light-curv…
The Supernova Legacy Survey 3-year sample: Type Ia Supernovae photometric distances and cosmological constraints
J. Guy, M. Sullivan, A. Conley +31
We present photometric properties and distance measurements of 252 high redshift Type Ia supernovae (0.15 < z < 1.1) discovered during the first three years of the Supernova Legacy…
Spectroscopic confirmation of a galaxy at redshift z=8.6
M. D. Lehnert, N. P. H. Nesvadba, J. -G. Cuby +6
Galaxies had their most significant impact on the Universe when they assembled their first generations of stars. Energetic photons emitted by young, massive stars in primeval galax…
The DAFT/FADA survey. I.Photometric redshifts along lines of sight to clusters in the z=[0.4,0.9] interval
L. Guennou, C. Adami, M. P. Ulmer +20
As a contribution to the understanding of the dark energy concept, the Dark energy American French Team (DAFT, in French FADA) has started a large project to characterize statistic…
Supernova Legacy Survey: Using Spectral Signatures To Improve Type Ia Supernovae As Distance Indicators
E. S. Walker, I. M. Hook, M. Sullivan +22
GMOS optical long-slit spectroscopy at the Gemini-North telescope was used to classify targets from the Supernova Legacy Survey (SNLS) from July 2005 and May 2006 - May 2008. Durin…
Real-time Analysis and Selection Biases in the Supernova Legacy Survey
K. Perrett, D. Balam, M. Sullivan +13
The Supernova Legacy Survey (SNLS) has produced a high-quality, homogeneous sample of Type Ia supernovae (SNe Ia) out to redshifts greater than z=1. In its first four years of full…
The Dependence of Type Ia Supernova Luminosities on their Host Galaxies
M. Sullivan, A. Conley, D. A. Howell +22
(Abridged) Precision cosmology with Type Ia supernovae (SNe Ia) makes use of the fact that SN Ia luminosities depend on their light-curve shapes and colours. Using Supernova Legacy…
Constraining dark matter halo properties using lensed SNLS supernovae
J. Jonsson, M. Sullivan, I. Hook +7
This paper exploits the gravitational magnification of SNe Ia to measure properties of dark matter haloes. The magnification of individual SNe Ia can be computed using observed pro…
Gravitational lensing in the Supernova Legacy Survey (SNLS)
T. Kronborg, D. Hardin, J. Guy +18
The observed brightness of Type Ia supernovae is affected by gravitational lensing caused by the mass distribution along the line of sight, which introduces an additional dispersio…
