Early-Time Ultraviolet and Optical Hubble Space Telescope Spectroscopy of the Type II Supernova 2022wsp
Sergiy S. Vasylyev, Christian Vogl, Yi Yang +9
We report early-time ultraviolet (UV) and optical spectroscopy of the young, nearby Type II supernova (SN) 2022wsp obtained by the Hubble Space Telescope (HST)/STIS at about 10 and…
Observations of the Very Young Type Ia Supernova 2019np with Early-excess Emission
Hanna Sai, Xiaofeng Wang, Nancy Elias-Rosa +30
Early-time radiative signals from type Ia supernovae (SNe Ia) can provide important constraints on the explosion mechanism and the progenitor system. We present observations and an…
Early-Time Ultraviolet Spectroscopy and Optical Follow-up Observations of the Type IIP Supernova 2021yja
Sergiy S. Vasylyev, Alexei V. Filippenko, Christian Vogl +19
We present three epochs of early-time ultraviolet (UV) and optical HST/STIS spectroscopy of the young, nearby Type IIP supernova (SN) 2021yja. We complement the HST data with two e…
Close, bright and boxy: the superluminous SN 2018hti
A. Fiore, S. Benetti, M. Nicholl +37
SN 2018hti was a very nearby (z=0.0614) superluminous supernova with an exceedingly bright absolute magnitude of -21.7 mag in r-band at maximum. The densely sampled pre-maximum lig…
Spectral modeling of type II supernovae II. A machine learning approach to quantitative spectroscopic analysis
C. Vogl, W. E. Kerzendorf, S. A. Sim +3
There are now hundreds of publicly available supernova spectral time series. Radiative transfer modeling of this data gives insights into the physical properties of these explosion…
The rise and fall of an extraordinary Ca-rich transient -- The discovery of ATLAS19dqr/SN 2019bkc
S. J. Prentice, K. Maguire, A. Flörs +25
This work presents the observations and analysis of ATLAS19dqr/SN 2019bkc, an extraordinary rapidly evolving transient event located in an isolated environment, tens of kiloparsecs…
