Gap Transients Interacting with Circumstellar Medium
Y. Cai, A. Reguitti, G. Valerin +1
In the last 20 years, modern wide-field surveys discovered a new class of peculiar transients, which lie in the luminosity gap between standard supernovae and classical novae. Thes…
Observations of the luminous red nova AT 2021biy in the nearby galaxy NGC 4631
Y. -Z. Cai, A. Pastorello, M. Fraser +73
We present an observational study of the luminous red nova (LRN) AT\,2021biy in the nearby galaxy NGC\,4631. The field of the object was routinely imaged during the pre-eruptive st…
Panchromatic evolution of three luminous red novae: Forbidden hugs in pandemic times -- IV
A. Pastorello, G. Valerin, M. Fraser +77
We present photometric and spectroscopic data on three extragalactic luminous red novae (LRNe): AT2018bwo, AT2021afy, and AT2021blu. AT2018bwo was discovered in NGC45 (at 6.8 Mpc)…
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…
SN 2021foa, a transitional event between a Type IIn (SN 2009ip-like) and a Type Ibn supernova
A. Reguitti, A. Pastorello, G. Pignata +16
We present photometric and spectroscopic data of the unusual interacting supernova (SN) 2021foa. It rose to an absolute magnitude peak of mag in 20 days. The initial ligh…
Low luminosity Type II supernovae -- IV. SN 2020cxd and SN 2021aai, at the edges of the sub-luminous supernovae class
G. Valerin, M. L. Pumo, A. Pastorello +20
Photometric and spectroscopic data for two Low Luminosity Type IIP Supernovae (LL SNe IIP) are presented. SN 2020cxd reaches a peak absolute magnitude = -13.90 0.05 m…
