Supernova Legacy Survey using spectral signatures to improve Type Ia supernovae as distance indicators. (2011)

Keywords : cosmology observations - supernovae: general

Abstract:Optical long-slit spectroscopy at the Gemini-North telescope using the Gemini Multi-Object Spectrograph (GMOS) was used to classify targets from the Supernova Legacy Survey (SNLS) from 2005 July and 2006 May-2008 May. During this time, 95 objects were observed. Where possible, the objects' redshifts (z) were measured from narrow emission or absorption features in the host galaxy spectrum, otherwise they were measured from the broader supernova features. We present spectra of 68 confirmed or probable SNe Ia from SNLS with redshifts in the range 0.17<=z<=1.02. ...(more)

Monthly Notices policies
The targets were selected from real-time SNLS imaging which took place at the Canada-France-Hawaii Telescope (CFHT). Fainter objects were usually observed spectroscopically at Gemini, with brighter candidates at either VLT or Keck.
