SN 2021fxy: Mid-Ultraviolet Flux Suppression is a Common Feature of Type Ia Supernovae
J. M. DerKacy, S. Paugh, E. Baron +26
We present ultraviolet (UV) to near-infrared (NIR) observations and analysis of the nearby Type Ia supernova SN 2021fxy. Our observations include UV photometry from Swift/UVOT, UV…
SN 2020wnt: a slow-evolving carbon-rich superluminous supernova with no O II lines and a bumpy light curve
C. P. Gutiérrez, A. Pastorello, M. Bersten +29
We present the analysis of SN 2020wnt, an unusual hydrogen-poor super-luminous supernova (SLSN-I), at a redshift of 0.032. The light curves of SN 2020wnt are characterised by an ea…
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…
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…
SN 2017gci: a nearby Type I Superluminous Supernova with a bumpy tail
Achille Fiore, Ting-Wan Chen, Anders Jerkstrand +26
We present and discuss the optical spectro-photometric observations of the nearby (z=0.087) Type I superluminous supernova (SLSN I) SN 2017gci, whose peak K-corrected absolute magn…
Photometric and spectroscopic evolution of the peculiar Type IIn SN 2012ab
Anjasha Gangopadhyay, Massimo Turatto, Stefano Benetti +15
We present an extensive ( 1200 d) photometric and spectroscopic monitoring of the Type IIn supernova (SN) 2012ab. After a rapid initial rise leading to a bright maximum (M$_{…
ASASSN-18am/SN 2018gk : An overluminous Type IIb supernova from a massive progenitor
Subhash Bose, Subo Dong, C. S. Kochanek +29
ASASSN-18am/SN 2018gk is a newly discovered member of the rare group of luminous, hydrogen-rich supernovae (SNe) with a peak absolute magnitude of mag that is in…
The transitional gap transient AT 2018hso: new insights on the luminous red nova phenomenon
Y-Z. Cai, A. Pastorello, M. Fraser +20
Aims: AT 2018hso is a new transient showing transitional properties between those of LRNe and the class of intermediate luminosity red transients (ILRTs) similar to SN 2008S. Throu…
