One year of broadband radio monitoring of the enigmatic transient GRB 250702B reveals the evolution of the relativistic jet
A. J. Goodwin, James C. A. Miller-Jones, Itai Sfaradi +19
We present an extensive radio monitoring campaign of the unique extragalactic transient GRB 250702B, with observations spanning 0.65-233 GHz from 6-356 d (observer frame) post-disc…
Tidal Disruption Events with the SKA
T. An, A. J. Goodwin, J. C. A. Miller-Jones +3
The paper outlines how the Square Kilometre Array’s sensitivity, wide frequency coverage, and VLBI capabilities will enable large‑scale radio studies of tidal disruption events, im…
Triple radio flares from tidal disruption events: jet-wind collisions and the discovery of a third radio flare from AT2020vwl
Andrew Mummery, Adelle Goodwin, Colin Christy +2
Radio flares from tidal disruption events (TDEs) are observed on two distinct timescales: prompt (around the time of optical peak) and delayed (hundreds to thousands of days after…
Radio Observations of the Unusual Tidal Disruption Event AT 2022wtn: a Fast and Highly Energetic Outflow
Gavin Farley, Tanmoy Laskar, Noah Franz +11
We present multi-epoch, multi-frequency radio observations of the tidal disruption event (TDE) AT 2022wtn, obtained with the Karl G. Jansky Very Large Array (VLA) and Giant Metrewa…
SKAO and Gamma-Ray Synergies
Gianluca Castignani, Gavin Rowell, Arnau Aguasca-Cabot +26
A wide variety of Galactic and extragalactic sources are known to emitradiation across the entire electromagnetic spectrum, including both transient and steady-state phenomena. A f…
VLA Observations Confirm AT 2023mfm as an Off-nuclear Tidal Disruption Event
Wenkai Li, Collin T. Christy, Kate D. Alexander +15
We report new radio observations of the tidal disruption event (TDE) AT 2023mfm, which we identified as a high-confidence candidate in a systematic search for off-nuclear TDEs. Hig…
