The Multi-Wavelength Context of Delayed Radio Emission in TDEs: Evidence for Accretion-Driven Outflows

Kate D. Alexander, Raffaella Margutti, Sebastian Gomez +20

Recent observations presented in Cendes et al. (2024a) show that optically selected tidal disruption events (TDEs) commonly produce delayed radio emission that can peak years post-…

Prospects for Observing Astrophysical Transients with GeV Neutrinos

Angelina Sherman, Jessie Thwaites, Ke Fang +2

Although Cherenkov detectors of high-energy neutrinos in ice and water are often optimized to detect TeV-PeV neutrinos, they may also be sensitive to transient neutrino sources in…

High-energy neutrino signatures from pulsar remnants of binary neutron-star mergers: coincident detection prospects with gravitational waves

Mainak Mukhopadhyay, Shigeo S. Kimura, Brian D. Metzger

Binary neutron-star (BNS) mergers are accompanied by multi-messenger emissions, including gravitational wave (GW), neutrino, and electromagnetic signals. Some fraction of BNS merge…

Evidence for Extended Hydrogen-Poor CSM in the Three-Peaked Light Curve of Stripped Envelope Ib Supernova

Yossef Zenati, Qinan Wang, Alexey Bobrick +40

We present multi-band ATLAS photometry for SN 2019tsf, a stripped-envelope Type Ib supernova (SESN). The SN shows a triple-peaked light curve and a late (re-)brightening, making it…

The origin of the coherent radio flash potentially associated with GRB 201006A

Nikhil Sarin, Teagan A. Clarke, Spencer J. Magnall +4

Rowlinson et al. 2023 recently claimed the detection of a coherent radio flash 76.6 minutes after a short gamma-ray burst. They proposed that the radio emission may be associated w…

Late-time HST and JWST Observations of GRB 221009A: Evidence for a Break in the Light Curve at 50 Days

Huei Sears, Ryan Chornock, Peter Blanchard +12

GRB 221009A is one of the brightest transients ever observed with the highest peak gamma-ray flux for a gamma-ray burst (GRB). A type Ic-BL supernova (SN), SN 2022xiw, was definiti…
