Evidence for a correlation between the Si II 4000 width and Type Ia supernova color

J. Nordin, L. Ostman, A. Goobar +8

We study the pseudo equivalent width of the Si II 4000 feature of Type Ia supernovae in the redshift range 0.0024 < z < 0.634. We find that this spectral indicator correlates with…

Non-linear gravitational clustering of cold matter in an expanding universe: indications from 1D toy models

Michael Joyce, François Sicard

Studies of a class of infinite one dimensional self-gravitating systems have highlighted that, on the one hand, the spatial clustering which develops may have scale invariant (frac…

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…

Cold uniform spherical collapse revisited

M. Joyce, B. Marcos, F. Sylos Labini

We report results of a study of the Newtonian dynamics of N self-gravitating particles which start in a quasi-uniform spherical configuration, without initial velocities. These ini…

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…

Dark energy constraints from a space-based supernova survey

P. Astier, J. Guy, R. Pain +1

We present a forecast of dark energy constraints that could be obtained from a large sample of distances to Type Ia supernovae detected and measured from space. We simulate the sup…

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…

Spectra and Light Curves of Six Type Ia Supernovae at 0.511 < z < 1.12 and the Union2 Compilation

R. Amanullah, C. Lidman, D. Rubin +42

We report on work to increase the number of well-measured Type Ia supernovae (SNe Ia) at high redshifts. Light curves, including high signal-to-noise HST data, and spectra of six S…

Nearby Supernova Factory Observations of SN 2007if: First Total Mass Measurement of a Super-Chandrasekhar-Mass Progenitor

R. A. Scalzo, G. Aldering, P. Antilogus +27

We present photometric and spectroscopic observations of SN 2007if, an overluminous (M_V = -20.4), red (B-V = 0.16 at B-band maximum), slow-rising (t_rise = 24 days) type Ia supern…

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…

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…
