On the diversity of strongly-interacting Type IIn supernovae
I. Salmaso, E. Cappellaro, L. Tartaglia +29
Massive stars experience strong mass-loss, producing a dense, H-rich circumstellar medium (CSM). After the explosion, the collision and continued interaction of the supernova (SN)…
The fast rise of the unusual Type IIL/IIb SN 2018ivc
A. Reguitti, R. Dastidar, G. Pignata +22
We present an analysis of the photometric and spectroscopic dataset of the Type II supernova (SN) 2018ivc in the nearby (10 Mpc) galaxy Messier 77. Thanks to the high cadence of th…
Massive stars exploding in a He-rich circumstellar medium X. Flash spectral features in the Type Ibn SN 2019cj and observations of SN 2018jmt
Z. -Y. Wang, A. Pastorello, K. Maeda +48
We present optical and near-infrared observations of two Type Ibn supernovae (SNe), SN 2018jmt and SN 2019cj. Their light curves have rise times of about 10 days, reaching an absol…
A study in scarlet -- II. Spectroscopic properties of a sample of Intermediate Luminosity Red Transients
G. Valerin, A. Pastorello, E. Mason +65
We investigate the spectroscopic characteristics of Intermediate Luminosity Red Transients (ILRTs), a class of elusive objects with peak luminosity between that of classical novae…
A study in scarlet -- I. Photometric properties of a sample of Intermediate Luminosity Red Transients
G. Valerin, A. Pastorello, A. Reguitti +57
We investigate the photometric characteristics of a sample of Intermediate Luminosity Red Transients (ILRTs), a class of elusive objects with peak luminosity between that of classi…
Red eminence: The intermediate-luminosity red transient AT 2022fnm
S. Moran, R. Kotak, M. Fraser +13
We present results from a five-month-long observing campaign of the unusual transient AT 2022fnm, which displays properties common to both luminous red novae (LRNe) and intermediat…
SN 2020pvb: a Type IIn-P supernova with a precursor outburst
Nancy Elias-Rosa, Seán J. Brennan, Stefano Benetti +37
We present photometric and spectroscopic data sets for SN 2020pvb, a Type IIn-P supernova (SN) similar to SNe 1994W, 2005cl, 2009kn and 2011ht, with a precursor outburst detected (…
JWST NIRSpec+MIRI Observations of the nearby Type IIP supernova 2022acko
M. Shahbandeh, C. Ashall, P. Hoeflich +65
We present JWST spectral and photometric observations of the Type IIP supernova (SN) 2022acko at ~50 days past explosion. These data are the first JWST spectral observations of a c…
The fast transient AT 2023clx in the nearby LINER galaxy NGC 3799 as a tidal disruption of a very low-mass star
P. Charalampopoulos, R. Kotak, T. Wevers +30
We present an extensive analysis of the optical and UV properties of AT2023clx, the closest TDE to date, that occurred in the nucleus of the interacting LINER galaxy, NGC3799 (z=0.…
