Type Ia supernova science 2010-2020
D. A. Howell, A. Conley, M. Della Valle +47
In the next decade Type Ia supernovae (SNe Ia) will be used to test theories predicting changes in the Dark Energy equation of state with time. Ultimately this requires a dedicated…
Type II Supernovae as Probes of Cosmology
Dovi Poznanski, Eddie Baron, Stephane Blondin +26
- Constraining the cosmological parameters and understanding Dark Energy have tremendous implications for the nature of the Universe and its physical laws. - The pervasive limit of…
SNLS Spectroscopy: Testing for Evolution in Type Ia Supernovae
T. J. Bronder, I. M. Hook, P. Astier +19
Aims: We present a quantitative study of a new data set of high redshift Type Ia supernovae spectra, observed at the Gemini telescopes during the first 34 months of the Supernova L…
The type Ia supernova SNLS-03D3bb from a super-Chandrasekhar-mass white dwarf star
D. Andrew Howell, Mark Sullivan, Peter E. Nugent +14
The acceleration of the expansion of the universe, and the need for Dark Energy, were inferred from the observations of Type Ia supernovae (SNe Ia). There is consensus that SNe Ia…
The Rise Time of Type Ia Supernovae from the Supernova Legacy Survey
A. Conley, D. A. Howell, A. Howes +24
We compare the rise times of nearby and distant Type Ia supernovae (SNe Ia) as a test for evolution using 73 high-redshift spectroscopically-confirmed SNe Ia from the first two yea…
Rates and properties of type Ia supernovae as a function of mass and star-formation in their host galaxies
M. Sullivan, D. Le Borgne, C. J. Pritchet +27
(ABRIDGED) We show that Type Ia supernovae (SNe Ia) are formed within both very young and old stellar populations, with observed rates that depend on the stellar mass and mean star…
