We present a novel technique for fitting restframe I-band light curves on a data set of 42 type la Supernovae (SNe Ia). Using the result of the fit, we construct a Hubble diagram with 26 SNe from the subset at 0.01 < z < 0.1. Adding two SNe at z ∼

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 Hubble Space Telescope data, and spectra of six SNe Ia that were discovered during 2001, are present

We develop a method to measure the strength of the absorption features in type la supernova (SN la) spectra and use it to make a quantitative comparisons between the spectra of type la supernovae at low and high redshifts. In this case study, we appl

Spectra of High-Redshift Type Ia Supernovae and a Comparison with Their Low-Redshift Counterparts**Much of the data presented herein were obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California, and the National Aeronautics and Space Administration. The Observatory was made possible by the generous financial support of the W. M. Keck Foundation. Also based in part on observations made with the European Southern Observatory telescopes (ESO programs 58.A-0745 and 59.A-0745)

We present spectra for 14 high-redshift (0.17 < z < 0.83) supernovae, which were discovered by the Supernova Cosmology Project as part of a campaign to measure cosmological parameters. The spectra are used to determine the redshift and classify the s
