The Type Ia Supernova Rate in Radio and Infrared Galaxies from the CFHT Supernova Legacy Survey
M. L. Graham, C. J. Pritchet, M. Sullivan +25
We have combined the large SN Ia database of the Canada-France-Hawaii Telescope Supernova Legacy Survey and catalogs of galaxies with photometric redshifts, VLA 1.4 GHz radio sourc…
Subaru FOCAS Spectroscopic Observations of High-Redshift Supernovae
Tomoki Morokuma, Kouichi Tokita, Christopher Lidman +30
We present spectra of high-redshift supernovae (SNe) that were taken with the Subaru low resolution optical spectrograph, FOCAS. These SNe were found in SN surveys with Suprime-Cam…
Photometric redshifts for supernovae Ia in the Supernova Legacy Survey
N. Palanque-Delabrouille, V. Ruhlmann-Kleider, S. Pascal +17
We present a method using the SALT2 light curve fitter to determine the redshift of Type Ia supernovae in the Supernova Legacy Survey (SNLS) based on their photometry in g', r', i'…
Weighing dark matter haloes with gravitationally lensed supernovae
Jakob Jonsson, Tomas Dahlen, Isobel Hook +2
High redshift Type Ia supernovae (SNe Ia) are likely to be gravitationally lensed by dark matter haloes of galaxies in the foreground. Since SNe Ia have very small dispersion after…
The ESO/VLT 3rd year Type Ia supernova data set from the Supernova Legacy Survey
C. Balland, S. Baumont, S. Basa +24
We present 139 spectra of 124 Type Ia supernovae (SNeIa) that were observed at the ESO/VLT during the first three years of the Canada-France-Hawai Telescope (CFHT) Supernova Legacy…
Photometric Calibration of the Supernova Legacy Survey Fields
N. Regnault, A. Conley, J. Guy +13
We present the photometric calibration of the Supernova Legacy Survey (SNLS) fields. The SNLS aims at measuring the distances to SNe Ia at (0.3<z<1) using MegaCam, the 1 deg^2 imag…
Constraining dust and color variations of high-z SNe using NICMOS on Hubble Space Telescope
S. Nobili, V. Fadeyev, G. Aldering +24
We present data from the Supernova Cosmology Project for five high redshift Type Ia supernovae (SNe Ia) that were obtained using the NICMOS infrared camera on the Hubble Space Tele…
The Core-collapse rate from the Supernova Legacy Survey
G. Bazin, N. Palanque-Delabrouille, J. Rich +27
We use three years of data from the Supernova Legacy Survey (SNLS) to study the general properties of core-collapse and type Ia supernovae. This is the first such study using the "…
