Snapping Supernovae at z>1.7
Greg Aldering, Alex G. Kim, Marek Kowalski +2
We examine the utility of very high redshift Type Ia supernovae for cosmology and systematic uncertainty control. Next generation space surveys such as the Supernova/Acceleration P…
Spectral diversity of Type Ia Supernovae
J. Berian James, Tamara M. Davis, Brian P. Schmidt +1
We use published spectroscopic and photometric data for 8 Type Ia supernovae to construct a dispersion spectrum for this class of object, showing their diversity over the wavelengt…
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…
