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…
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…
TDE 2025abcr: A Tidal Disruption Event in the Outskirts of a Massive Galaxy
Robert Stein, Jonathan Carney, Charlotte Ward +27
Tidal disruption events (TDEs) have traditionally been discovered in optical sky surveys through targeted searches of nuclear transients. However, it is expected that some TDEs wil…

The observational link between long gamma-ray bursts (GRBs) and broad-lined stripped-envelope core-collapse supernovae (SNe Ic-BL) is well established. Significant progress has bee…
A New FU Orionis Accretion Outburst in the W5 HII Region
Lynne A. Hillenbrand, Matthew J. Graham, Mansi M. Kasliwal +9
