Journal ArticleDOI
Gravitational lensing in the supernova legacy survey (SNLS)
T. Kronborg,T. Kronborg,D. Hardin,Julien Guy,Pierre Astier,Christophe Balland,Stéphane Basa,Raymond G. Carlberg,A. Conley,Dominique Fouchez,I. M. Hook,I. M. Hook,D. A. Howell,D. A. Howell,Jakob Jonsson,Reynald Pain,Kristian Pedersen,Kathy Perrett,Christopher J. Pritchet,Nicolas Regnault,J. Rich,Mark Sullivan,Nathalie Palanque-Delabrouille,V. Ruhlmann-Kleider +23 more
TL;DR: In this article, the authors investigate the correlation between the residuals from the Hubble diagram and the gravitational magnification based on a modeling of the mass distribution of foreground galaxies and find evidence of a lensing signal with a 2.3 sigma significance.

Wood-Vasey,W. M. Wood-Vasey,Naoki Yasuda +54 more
TL;DR: In this article, the authors presented VLT FORS1 and FORS2 spectra of 39 candidate high-redshift supernovae that were discovered as part of a cosmological study using type Ia supernova (SNe Ia) over a wide range of redshifts.
Journal ArticleDOI
A survey for high-redshift radio-loud quasars: optical spectroscopy of S > 0.2 Jy, flat-spectrum radio sources
TL;DR: In this article, the authors present optical spectroscopic data for a complete sample of 161 S_5GHz >= 0.2 Jy, flat-spectrum radio sources, which were observed as part of a survey for high redshift, radio-loud quasars.
Journal ArticleDOI

TL;DR: In this paper, the Canada-France-Hawaii Telescope Supernova Legacy Survey (CFHT SNLS) has created a large homogeneous database of intermediate redshift (0.2 < z < 1.0) type Ia supernovae (SNe Ia), and correlations exist between SN Ia rates, properties, and host galaxy star-formation rates (SFRs).
Journal ArticleDOI

Lidman,Saul Perlmutter,P. Ripoche,Emma S. Walker +28 more
TL;DR: In this article, the authors presented a sample of 485 photometrically identified Type Ia supernova candidates mined from the first three years of data of the CFHT SuperNova Legacy Survey (SNLS).
