An Agnostic Approach to Building Empirical Type Ia Supernova Light Curves: Evidence for Intrinsic Chromatic Flux Variation Using Nearby Supernova Factory Data

Jared Hand, A. G. Kim, G. Aldering +35

We present a new empirical Type Ia supernova (SN Ia) model with three chromatic flux variation templates: one phase dependent and two phase independent. No underlying dust extincti…

SN 2012dn from early to late times: 09dc-like supernovae reassessed

S. Taubenberger, A. Floers, C. Vogl +40

As a candidate 'super-Chandrasekhar' or 09dc-like Type Ia supernova (SN Ia), SN 2012dn shares many characteristics with other members of this remarkable class of objects but lacks…

Oxygen and helium in stripped-envelope supernovae

C. Fremling, J. Sollerman, M. M. Kasliwal +23

We present an analysis of 507 spectra of 173 stripped-envelope (SE) supernovae (SNe) discovered by the untargeted Palomar Transient Factory (PTF) and intermediate PTF (iPTF) survey…

Understanding Type Ia supernovae through their U-band spectra

J. Nordin, G. Aldering, P. Antilogus +39

Context. Observations of Type Ia supernovae (SNe Ia) can be used to derive accurate cosmological distances through empirical standardization techniques. Despite this success neithe…

Exploring the spectral diversity of low-redshift Type Ia supernovae using the Palomar Transient Factory

Kate Maguire, Mark Sullivan, Yen-Chen Pan +15

We present an investigation of the optical spectra of 264 low-redshift (z < 0.2) Type Ia supernovae (SNe Ia) discovered by the Palomar Transient Factory, an untargeted transient su…
