Quantitative comparison between Type Ia supernova spectra at low and high redshifts: A case study
G. Garavini, G. Folatelli, S. Nobili +44
We develop a method to measure the strength of the absorption features in Type Ia supernova (SN Ia) spectra and use it to make a quantitative comparison between the spectra of Type…
Measurement of Ω_m, Ω_Λ from a blind analysis of Type Ia supernovae with CMAGIC: Using color information to verify the acceleration of the Universe
A. Conley, G. Goldhaber, L. Wang +26
We present measurements of Ω_m and Ω_Λ from a blind analysis of 21 high-redshift supernovae using a new technique (CMAGIC) for fitting the multi-color lightcurves of Type Ia supern…
Spectra of High-Redshift Type Ia Supernovae and a Comparison with their Low-Redshift Counterparts
I. M. Hook, D. A. Howell, G. Aldering +32
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 paramet…
Spectroscopic Observations and Analysis of the Unusual Type Ia SN 1999ac
The Supernova Cosmology Project, :, G. Garavini +55
We present optical spectra of the peculiar Type Ia supernova (SN Ia) 1999ac. The data extend from -15 to +42 days with respect to B-band maximum and reveal an event that is unusual…
Restframe I-band Hubble diagram for type Ia supernovae up to redshift z ~0.5
The Supernova Cosmology Project, :, S. Nobili +35
We present a novel technique for fitting restframe I-band light curves on a data set of 42 Type Ia supernovae (SNe Ia). Using the result of the fit, we construct a Hubble diagram w…
Spectroscopic confirmation of high-redshift supernovae with the ESO VLT
C. Lidman, D. A. Howell, G. Folatelli +44
We present VLT FORS1 and FORS2 spectra of 39 candidate high-redshift supernovae that were discovered as part of a cosmological study using Type Ia supernovae (SNe Ia) over a wide r…
