Probing type Ia supernova properties using bolometric light curves from the Carnegie Supernova Project and the CfA Supernova Group
Richard A. Scalzo, Emilie Parent, Christopher Burns +11
We present bolometric light curves constructed from multi-wavelength photometry of Type Ia supernovae (SNe Ia) from the Carnegie Supernova Project and the CfA Supernova Group, usin…
The ASAS-SN Bright Supernova Catalog -- IV. 2017
T. W. -S. Holoien, J. S. Brown, P. J. Vallely +41
In this catalog we compile information for all supernovae discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN) as well as all other bright (), spectr…
Carnegie Supernova Project-II: Extending the Near-Infrared Hubble Diagram for Type Ia Supernovae to
M. M. Phillips, Carlos Contreras, E. Y. Hsiao +41
The Carnegie Supernova Project-II (CSP-II) was an NSF-funded, four-year program to obtain optical and near-infrared observations of a "Cosmology" sample of Type Ia supern…
Investigating the Unusual Spectroscopic Time-Evolution in SN 2012fr
C. Cain, E. Baron, M. M. Phillips +9
The type Ia supernova (SN) 2012fr displayed an unusual combination of its Si II λλ5972, 6355 features. This includes the ratio of their pseudo equivalent widths, placing it at the…
Strongly Bipolar Inner Ejecta of the Normal Type IIP Supernova ASASSN-16at
Subhash Bose, Subo Dong, N. Elias-Rosa +24
We report distinctly double-peakedH-alpha and H-beta emission lines in the late-time, nebular-phase spectra (>~200 d) of the otherwise normal at early phases (<~ 100 d) Type IIP su…
Carnegie Supernova Project-II: The Near-infrared Spectroscopy Program
E. Y. Hsiao, M. M. Phillips, G. H. Marion +42
Shifting the focus of Type Ia supernova (SN Ia) cosmology to the near-infrared (NIR) is a promising way to significantly reduce the systematic errors, as the strategy minimizes our…
