The morphology of the ejecta of SN 1987A at 31 years from 1150 to 10000 Å
Tuomas Kangas, Claes Fransson, Josefin Larsson +7
We present spectroscopy of the ejecta of SN 1987A in 2017 and 2018 from the Hubble Space Telescope and the Very Large Telescope, covering the wavelength range between and $1…
The Pantheon+ Analysis: The Full Dataset and Light-Curve Release
Dan Scolnic, Dillon Brout, Anthony Carr +27
Here we present 1701 light curves of 1550 spectroscopically confirmed Type Ia supernovae (SNe Ia) that will be used to infer cosmological parameters as part of the Pantheon+ SN ana…
Carnegie Supernova Project-II: Near-infrared Spectroscopy of Stripped-Envelope Core-Collapse Supernovae
M. Shahbandeh, E. Y. Hsiao, C. Ashall +29
We present 75 near-infrared (NIR; 0.82.5 m) spectra of 34 stripped-envelope core-collapse supernovae (SESNe) obtained by the Carnegie Supernova Project-II (CSP-II), encompass…
ASASSN-15hy: an under-luminous, red 03fg-like type Ia supernova
J. Lu, C. Ashall, E. Y. Hsiao +33
We present photometric and spectroscopic observations of the 03fg-like type Ia supernova (SN Ia) ASASSN-15hy from the ultraviolet (UV) to the near-infrared (NIR). ASASSN-15hy share…
Carnegie Supernova Project: The First Homogeneous Sample of "Super-Chandrasekhar Mass"/2003fg-like Type Ia Supernova
C. Ashall, J. Lu, E. Y. Hsiao +38
We present a multi-wavelength photometric and spectroscopic analysis of thirteen "Super-Chandrasekhar Mass"/2003fg-like type Ia Supernova (SNe~Ia). Nine of these objects were obser…
Still Brighter than Pre-Explosion, SN 2012Z Did Not Disappear: Comparing Hubble Space Telescope Observations a Decade Apart
Curtis McCully, Saurabh W. Jha, Richard A. Scalzo +10
Type Iax supernovae represent the largest class of peculiar white-dwarf supernovae. The type Iax SN~2012Z in NGC 1309 is the only white dwarf supernova with a detected progenitor s…
