Precise Measurements of Self-absorbed Rising Reverse Shock Emission from Gamma-ray Burst 221009A
Joe S. Bright, Lauren Rhodes, Wael Farah +18
The deaths of massive stars are sometimes accompanied by the launch of highly relativistic and collimated jets. If the jet is pointed towards Earth, we observe a "prompt" gamma-ray…
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 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…
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…
