The HST See Change Program: I. Survey Design, Pipeline, and Supernova Discoveries
Brian Hayden, David Rubin, Kyle Boone +53
The See Change survey was designed to make cosmological measurements by efficiently discovering high-redshift Type Ia supernovae (SNe Ia) and improving cluster mass measureme…
SUGAR: An improved empirical model of Type Ia Supernovae based on spectral features
P. -F. Léget, E. Gangler, F. Mondon +40
Type Ia Supernovae (SNe Ia) are widely used to measure the expansion of the Universe. Improving distance measurements of SNe Ia is one technique to better constrain the acceleratio…
SNEMO: Improved Empirical Models for Type Ia Supernovae
C. Saunders, G. Aldering, P. Antilogus +39
Type Ia supernova cosmology depends on the ability to fit and standardize observations of supernova magnitudes with an empirical model. We present here a series of new models of Ty…
Strong Dependence of Type Ia Supernova Standardization on the Local Specific Star Formation Rate
M. Rigault, V. Brinnel, G. Aldering +40
As part of an on-going effort to identify, understand and correct for astrophysics biases in the standardization of Type Ia supernovae (SNIa) for cosmology, we have statistically c…
Correcting for peculiar velocities of Type Ia Supernovae in clusters of galaxies
P. -F. Léget, M. V. Pruzhinskaya, A. Ciulli +43
Type Ia Supernovae (SNe Ia) are widely used to measure the expansion of the Universe. To perform such measurements the luminosity and cosmological redshift () of the SNe Ia have…
