The matter beyond the ring: the recent evolution of SN 1987A observed by the Hubble Space Telescope
J. Larsson, C. Fransson, D. Alp +14
The nearby SN 1987A offers a spatially resolved view of the evolution of a young supernova remnant. Here we precent recent Hubble Space Telescope imaging observations of SN 1987A,…
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…
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…
Supernova Photometric Classification Pipelines Trained on Spectroscopically Classified Supernovae from the Pan-STARRS1 Medium-Deep Survey
V. A. Villar, E. Berger, G. Miller +11
Photometric classification of supernovae (SNe) is imperative as recent and upcoming optical time-domain surveys, such as the Large Synoptic Survey Telescope (LSST), overwhelm the a…
Carnegie Supernova Project-II: Using Near-Infrared Spectroscopy to determine the location of the outer Ni in Type Ia Supernovae
C. Ashall, E. Y. Hsiao, P. Hoeflich +17
We present the -band wavelength region of thirty post-maximum light near-infrared (NIR) spectra of fourteen transitional and sub-luminous type Ia supernovae (SNe Ia), extending…
Type Ia Supernovae are Excellent Standard Candles in the Near-Infrared
Arturo Avelino, Andrew S. Friedman, Kaisey S. Mandel +3
We analyze a set of 89 Type Ia supernovae (SN Ia) that have both optical and near-infrared (NIR) photometry to derive distances and construct low redshift () Hubble diagr…
