Carnegie Supernova Project II: The slowest rising Type Ia supernova LSQ14fmg and clues to the origin of super-Chandrasekhar/03fg-like events

E. Y. Hsiao, P. Hoeflich, C. Ashall +34

The Type Ia supernova (SN Ia) LSQ14fmg exhibits exaggerated properties which may help to reveal the origin of the "super-Chandrasekhar" (or 03fg-like) group. The optical spectrum i…

Carnegie Supernova Project-II: A new method to photometrically identify sub-types of extreme Type Ia Supernovae

C. Ashall, J. Lu, C. Burns +16

We present a new method to photometrically delineate between various sub-types of type Ia supernovae (SNe Ia). Using the color-stretch parameters, or , and the tim…

Carnegie Supernova Project-II: Near-infrared Spectroscopic Diversity of Type II Supernovae

S. Davis, E. Y. Hsiao, C. Ashall +24

We present near-infrared (NIR) spectra of Type II supernovae (SNe II) from the Carnegie Supernova Project-II (CSP-II), the largest such dataset published to date. We iden…

Comparison of the optical light curves of hydrogen-rich and hydrogen-poor type II supernovae

P. J. Pessi, G. Folatelli, J. P. Anderson +12

Type II supernovae (SNe II) show strong hydrogen features in their spectra throughout their whole evolution while type IIb supernovae (SNe IIb) spectra evolve from dominant hydroge…

SN 2017gmr: An energetic Type II-P supernova with asymmetries

Jennifer E. Andrews, D. J. Sand, S. Valenti +77

We present high-cadence ultraviolet (UV), optical, and near-infrared (NIR) data on the luminous Type II-P supernova SN 2017gmr from hours after discovery through the first 180 days…

A Physical Basis for the H-band Blue-edge Velocity and Light-Curve Shape Correlation in Context of Type Ia Supernova Explosion Physics

C. Ashall, P. Hoeflich, E. Y. Hsiao +17

Our recent work demonstrates a correlation between the high-velocity blue edge, , of the iron-peak Fe/Co/Ni -band emission feature and the optical light curve shape of…
