Time-dependent modelling of short-term variability in the TeV-blazar VER J0521+211 during the major flare in 2020

MAGIC Collaboration, S. Abe, J. Abhir +228

The BL Lacertae object VER J0521+211 underwent a notable flaring episode in February 2020. A short-term monitoring campaign, led by the MAGIC (Major Atmospheric Gamma Imaging Chere…

Unveiling the nature of SN 2022jli: The first double-peaked stripped-envelope supernova showing periodic undulations and dust emission at late times

Régis Cartier, Carlos Contreras, Maximilian Stritzinger +6

We present optical and infrared observations from maximum light until around +800 days of supernova (SN) 2022jli, a peculiar stripped-envelope (SE) SN showing two maxima, each one…

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 metamorphosis of the Type Ib SN 2019yvr: late-time interaction

Lucía Ferrari, Gastón Folatelli, Hanindyo Kuncarayakti +32

We present observational evidence of late-time interaction between the ejecta of the hydrogen-poor Type Ib supernova (SN) 2019yvr and hydrogen-rich circumstellar material (CSM), si…

Discovery and Follow-up of ASASSN-23bd (AT 2023clx): The Lowest Redshift and Least Luminous Tidal Disruption Event To Date

W. B. Hoogendam, J. T. Hinkle, B. J. Shappee +23

We report the All-Sky Automated Survey for SuperNovae discovery of the tidal disruption event (TDE) ASASSN-23bd (AT 2023clx) in NGC 3799, a LINER galaxy with no evidence of strong…
