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…
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…
Improving Cosmological Distance Measurements Using Twin Type Ia Supernovae
H. K. Fakhouri, K. Boone, G. Aldering +41
We introduce a method for identifying "twin" Type Ia supernovae, and using them to improve distance measurements. This novel approach to Type Ia supernova standardization is made p…
Confirmation of a Star Formation Bias in Type Ia Supernova Distances and its Effect on Measurement of the Hubble Constant
M. Rigault, G. Aldering, M. Kowalski +35
Previously we used the Nearby Supernova Factory sample to show that SNe~Ia having locally star-forming environments are dimmer than SNe~Ia having locally passive environments.Here…
Type Ia Supernova Hubble Residuals and Host-Galaxy Properties
A. G. Kim, G. Aldering, P. Antilogus +33
Kim et al. (2013) [K13] introduced a new methodology for determining peak-brightness absolute magnitudes of type Ia supernovae from multi-band light curves. We examine the relation…
Evidence of Environmental Dependencies of Type Ia Supernovae from the Nearby Supernova Factory indicated by Local Hα
M. Rigault, Y. Copin, G. Aldering +33
(Abridged) We study the host galaxy regions in close proximity to Type Ia supernovae (SNe Ia) to analyze relations between the properties of SN Ia events and environments most simi…
