The fraction of periodic SN Ib/c light curves
Asaf Horowicz, Eran O. Ofek, Avishay Gal-Yam
Periodic luminosity modulations have been recently identified for the stripped-envelope supernovae SN 2022jli and SN 2022esa, motivating a systematic search for a similar behavior…
AT 2022csn: A Photometrically Peculiar Optical/UV Tidal Disruption Event in a Type II AGN
Yael Dgany, Iair Arcavi, Grisha Zeltyn +18
The emission mechanism and host galaxy preference of optical/UV tidal disruption events (TDEs) are still not entirely understood. We present observations of the TDE AT 2022csn, whi…
Dust Without Na I D Trace: The Case of Highly Attenuated Type Ib SN 2024vjc
Javier Silva-Farfán, Keiichi Maeda, Andrea Pastorello +19
Understanding dust attenuation toward extragalactic transients is critical for recovering their intrinsic properties and probing the local environments of distant galaxies. A popul…
SN 2020bij and a Possible Slow-Rise High-Velocity Subclass of Type IIP Supernovae
Sondos Mohsen-Tanev, Iair Arcavi, Shahar Bracha +17
Mapping how the explosion properties of Type II supernovae (SNe II) relate to the properties of their progenitors can provide strong constraints for understanding the final evoluti…
Detection of persistent helium absorption in the 91bg-like type Ia Supernova 2022an
Ping Chen, Avishay Gal-Yam, Subo Dong +14
We present optical and near-infrared observations of the fast-declining Type Ia supernova (SN Ia) 2022an. The photometric and spectroscopic properties identify it as a standard 91b…
SN~2018erx: A fast-evolving, dust-reddened Type Icn supernova with broad C II emission lines
Kaustav K. Das, Anjasha Gangopadhyay, Mansi M. Kasliwal +17
We present the discovery and characterization of SN~2018erx (ZTF18abkmbpy), a fast-evolving, unusually red, interacting stripped-envelope supernova. Spectroscopically, SN~2018erx s…
