The dense and non-homogeneous circumstellar medium revealed in radio wavelengths around the Type Ib SN 2019oys

Itai Sfaradi, Assaf Horesh, Jesper Sollerman +7

We present here broadband radio observations of the CSM interacting SN2019oys. SN2019oys was first detected in the optical and was classified as a Type Ib SN. Then, about $\sim 100…

An off-axis relativistic jet seen in the long lasting delayed radio flare of the TDE AT 2018hyz

Itai Sfaradi, Paz Beniamini, Assaf Horesh +8

The Tidal Disruption Event (TDE) AT 2018hyz exhibited a delayed radio flare almost three years after the stellar disruption. Here we report new radio observations of the TDE AT 201…

Luminous Radio Emission from the Superluminous Supernova 2017ens at 3.3 years after explosion

Raffaella Margutti, J. S. Bright, D. J. Matthews +17

We present the results from a multi-year radio campaign of the superluminous supernova (SLSN) 2017ens, which yielded the earliest radio detection of a SLSN to date at the age of $\…

AT 2021loi: A Bowen Fluorescence Flare with a Rebrightening Episode, Occurring in a Previously-Known AGN

Lydia Makrygianni, Benny Trakhtenbrot, Iair Arcavi +12

AT 2021loi is an optical-ultraviolet transient located at the center of its host galaxy. Its spectral features identify it as a member of the ``Bowen Fluorescence Flare'' (BFF) cla…

Evidence for a black hole spin--orbit misalignment in the X-ray binary Cyg X-1

Andrzej A. Zdziarski, Alexandra Veledina, Michal Szanecki +3

Recently, the accretion geometry of the black-hole X-ray binary Cyg X-1 was probed with the X-ray polarization. The position angle of the X-ray emitting flow was found to be aligne…
