Dinosaur in a Haystack : X-ray View of the Entrails of SN 2023ixf and the Radio Afterglow of Its Interaction with the Medium Spawned by the Progenitor Star (Paper 1)
A. J. Nayana, Raffaella Margutti, Eli Wiston +24
We present the results from our extensive hard-to-soft X-ray (NuSTAR, Swift-XRT, XMM-Newton, Chandra) and meter-to-mm wave radio (GMRT, VLA, NOEMA) monitoring campaign of the very…
SN 2021foa: the bridge between SN IIn and Ibn
Anjasha Gangopadhyay, Naveen Dukiya, Takashi J Moriya +26
We present the long-term photometric and spectroscopic analysis of a transitioning SN~IIn/Ibn from 10.8 d to 150.7 d post -band maximum. SN~2021foa shows prominent He {\sc i}…
The unluckiest star: A spectroscopically confirmed repeated partial tidal disruption event AT 2022dbl
Zheyu Lin, Ning Jiang, Tinggui Wang +13
The unluckiest star orbits a supermassive black hole elliptically. Every time it reaches the pericenter, it shallowly enters the tidal radius and gets partially tidal disrupted, pr…
STELLA lightcurves of energetic pair instability supernovae in the context of SN2018ibb
Chris Nagele, Hideyuki Umeda, Keiichi Maeda
SN2018ibb is a recently observed hydrogen poor super-luminous supernova which appears to be powered by the decay of of radioactive nickel. This supernova has bee…
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…
The enigmatic double-peaked stripped-envelope SN 2023aew
Tuomas Kangas, Hanindyo Kuncarayakti, Takashi Nagao +29
We present optical and near-infrared photometry and spectroscopy of SN 2023aew and our findings on its remarkable properties. This event, initially resembling a Type IIb supernova…
