An Off-Nuclear Tidal Disruption Event Discovered At Late Times: The Case Of TDE 2023mfm
Itai Sfaradi, Ryan Chornock, Yuhan Yao +24
We present the discovery and analysis of the optically selected tidal disruption event (TDE) 2023mfm, which originates from a wandering massive black hole (MBH) in a massive ($\sim…
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 +18
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…
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…
Late-time JWST/NIRCam Observations of the Extremely Long-duration GRB 250702B/EP 250702a and Its Host Galaxy
Huei Sears, Jean J. Somalwar, Ryan Chornock +22
We present JWST/NIRCam observations of the extremely long-duration gamma-ray burst (GRB) 250702B taken at ~ 95 days post-GRB (observer frame). The observations of the host galaxy r…
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…
Rapid-response 1.3 mm Observations of GRB 260127A with the Submillimeter Array
Garrett K. Keating, Tanmoy Laskar, Anna Y. Q. Ho +9
We present the results from rapid-response 1.3 mm observations of GRB 260127A using the Submillimeter Array (SMA). SMA arrived on-source 12.6 minutes after the initial detection by…
A 14-year-old Mystery: The Peculiar Case of the Engine-driven SN 2012ap
Itai Sfaradi, Raffaella Margutti, Ryan Chornock +29
We present late-time ( d) optical (Keck), X-ray (Chandra and NuSTAR), and radio (VLA, ALMA, and the uGMRT) observations of the Type Ic-BL SN 2012ap. Previous studies of…
AT2024lhc and AT2024kmq in the landscape of featureless tidal disruption events
Yuhan Yao, Ryan Chornock, Andrew Mummery +39
We study AT2024kmq and AT2024lhc, two tidal disruption events (TDEs) with blue featureless spectra associated with high-mass black holes (). Both even…
SN 2024abfl: A Flat-Plateau, Low-Luminosity Type IIP Supernova with Early CSM Interaction
Madison Gerard, Jennifer E. Andrews, Geoffrey C. Clayton +29
We present photometric and spectroscopic observations of SN 2024abfl, a low-luminosity Type IIP supernova (LLSN) discovered shortly after explosion. The transient reached a peak ab…
