The First Radio-Bright Off-Nuclear TDE 2024tvd Reveals the Fastest-Evolving Double-Peaked Radio Emission
Itai Sfaradi, Raffaella Margutti, Ryan Chornock +34
We present the first multi-epoch broadband radio and millimeter monitoring of an off-nuclear TDE using the VLA, ALMA, ATA, AMI-LA, and the SMA. The off-nuclear TDE 2024tvd exhibits…
Thermal electrons in the radio afterglow of relativistic tidal disruption event ZTF22aaajecp/AT2022cmc
Lauren Rhodes, Ben Margalit, Joe S. Bright +11
A tidal disruption event (TDE) occurs when a star travels too close to a supermassive black hole. In some cases, accretion of the disrupted material onto the black hole launches a…
The observed phase space of mass-loss history from massive stars based on radio observations of a large supernova sample
Itai Sfaradi, Assaf Horesh, Rob Fender +4
In this work we study the circumstellar material (CSM) around massive stars, and the mass-loss rates depositing this CSM, using a large sample of radio observations of 325 core-col…
Filling the radio transients gap (or: The case for a dedicated radio transients monitoring array in the southern hemisphere)
Rob Fender, Assaf Horesh, Phil Charles +3
In this short paper we outline the case for a small radio telescope array in the southern hemisphere with operations dedicated to rapid follow-up and monitoring of astrophysical tr…
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…
