VLASS Discovery of a Luminous Galactic Radio Transient Evolving on Decade Timescales

Jessie M. Miller, Gregg Hallinan, Dillon Dong +10

We present a multiwavelength analysis of the radio transient VT J1906+0849, discovered as a 70 mJy source in Epoch 1 of the Very Large Array Sky Survey (VLASS), 21 yr after an NRAO…

A spectacular multi-wavelength transient associated with an off-axis relativistic jet

Delina Levine, Gregg Hallinan, Jean J. Somalwar +10

Many of the most luminous extragalactic transients originate from the accretion of material onto a black hole (BH) via core-collapse, stellar mergers, or the tidal disruption of a…

Long GRB 250916A: an Off-axis Powerlaw Jet with Thermal Cocoon

Utkarsh Pathak, Sameer K. Patil, Hitesh Tanenia +22

Some gamma-ray bursts (GRBs) exhibit precursor emission episodes preceding the main emission, with a quiescent period in between. The properties of the precursor emission and the d…

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…

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 Double Tidal Disruption Event AT 2022dbl Implies That at Least Some "Standard" Optical TDEs are Partial Disruptions

Lydia Makrygianni, Iair Arcavi, Megan Newsome +37

Flares produced following the tidal disruption of stars by supermassive black holes can reveal the properties of the otherwise dormant majority of black holes and the physics of ac…
