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…

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…

The Radio Properties of Extreme Coronal Line Emitters: Constraints on the Sub-parsec Environment

Noah Franz, Kate D. Alexander, Collin T. Christy +10

A tiny fraction () of galaxies display luminous, high-ionization metal emission lines, which may be persistent or variable. These extreme coronal lines (ECLs) are produced…

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…

Old and Bright: The Remarkable Radio Brightening of the Engine-driven SN 2012au Several Years After Explosion Signals the Birth of a PWN

Eli Wiston, Raffaella Margutti, A. J. Nayana +23

We present the results from an extensive broad-band (radio to X-rays) observing campaign of the engine-driven Type Ib SN 2012au in the first 13 years of evolution. The early-time (…

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…

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…

Search For a Counterpart to the Subsolar Mass Gravitational Wave Candidate S251112cm

Nicholas Vieira, Noah Franz, Bhagya Subrayan +49

The recent candidate gravitational-wave (GW) alert from a compact object merger involving at least one subsolar mass (SSM) object has prompted questions about their origins. S25111…
