The SNEMO and SUGAR Companion Datasets
G. Aldering, P. Antilogus, C. Aragon +41
The Nearby Supernova Factory has made spectrophotometric observations of Type Ia supernovae since . This work presents an interim version of the data produced, including $210…
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…
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…
