SN 2019muj -- a well-observed Type Iax supernova that bridges the luminosity gap of the class
Barnabás Barna, Tamás Szalai, Saurabh W. Jha +38
We present early-time ( days) observations of SN 2019muj (= ASASSN-19tr), one of the best-observed members of the peculiar SN Iax class. Ultraviolet and optical photometri…
An investigation of Ni shells as the source of early light curve bumps in type Ia supernovae
M. R. Magee, K. Maguire
An excess of flux (i.e. a bump) in the early light curves of type Ia supernovae has been observed in a handful of cases. Multiple scenarios have been proposed to explain this. It h…
The Spectacular Ultraviolet Flash From the Peculiar Type Ia Supernova 2019yvq
A. A. Miller, M. R. Magee, A. Polin +42
Early observations of Type Ia supernovae (SNeIa) provide essential clues for understanding the progenitor system that gave rise to the terminal thermonuclear explosion. We pres…
Observations of the low-luminosity Type Iax supernova 2019gsc: a fainter clone of SN 2008ha?
Lina Tomasella, Maximilian Stritzinger, Stefano Benetti +9
We present optical photometric and spectroscopic observations of the faint-and-fast evolving type Iax SN 2019gsc, extending from the time of g-band maximum until about fifty days p…
DES16C3cje: A low-luminosity, long-lived supernova
C. P. Gutiérrez, M. Sullivan, L. Martinez +89
We present DES16C3cje, a low-luminosity, long-lived type II supernova (SN II) at redshift 0.0618, detected by the Dark Energy Survey (DES). DES16C3cje is a unique SN. The spectra a…
