An improved standardization framework for Type II-P supernovae using a hierarchical Bayesian approach

A. Holas, S. Taubenberger, C. Vogl +41

We use Type II-P supernovae (SNe II-P) observed as part of the Nearby Supernova Factory (SNfactory) experiment as standardizable candles to develop an improved standardization fram…

A Probabilistic Autoencoder for Type Ia Supernovae Spectral Time Series

George Stein, Uros Seljak, Vanessa Bohm +37

We construct a physically-parameterized probabilistic autoencoder (PAE) to learn the intrinsic diversity of type Ia supernovae (SNe Ia) from a sparse set of spectral time series. T…

The Twins Embedding of Type Ia Supernovae I: The Diversity of Spectra at Maximum Light

K. Boone, G. Aldering, P. Antilogus +34

We study the spectral diversity of Type Ia supernovae (SNe Ia) at maximum light using high signal-to-noise spectrophotometry of 173 SNe Ia from the Nearby Supernova Factory. We dec…

The Twins Embedding of Type Ia Supernovae II: Improving Cosmological Distance Estimates

K. Boone, G. Aldering, P. Antilogus +34

We show how spectra of Type Ia supernovae (SNe Ia) at maximum light can be used to improve cosmological distance estimates. In a companion article, we used manifold learning to bui…

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…
