Nine tidal disruption event candidates in eROSITA-DE DR1 discovered through supersoft X-ray selection
R. A. J. Eyles-Ferris, R. L. C. Starling, P. T. O'Brien +2
Tidal disruption events are rare and diverse transients that occur when a star is torn apart by a supermassive black hole and accreted, which can result in a supersoft X-ray therma…
The day-long, repeating GRB 250702BDE / EP250702a: A unique extragalactic transient
Andrew J. Levan, Antonio Martin-Carrillo, Tanmoy Laskar +42
Gamma-ray bursts (GRBs) are singular outbursts of high-energy radiation with durations typically lasting from milliseconds to minutes and, in extreme cases, a few hours. They are a…
The kangaroo's first hop: the early fast cooling phase of EP250108a/SN 2025kg
Rob A. J. Eyles-Ferris, Peter G. Jonker, Andrew J. Levan +52
Fast X-ray transients (FXTs) are a rare and poorly understood population of events. Previously difficult to detect in real time, the launch of the Einstein Probe with its wide fiel…
First joint absorption and T-based metallicity measured in a GRB host galaxy at using JWST/NIRSpec
Anne Inkenhaag, Patricia Schady, Phil Wiseman +20
We present the first gamma-ray burst (GRB) host galaxy with a measured absorption line and electron temperature (T) based metallicity, using the temperature sensitive [OIII]$λ…
Prompt Periodicity in the GRB 211211A Precursor: Black-hole or magnetar engine?
Gavin P. Lamb, Thomas Baxter, Conor M. B. Omand +18
The merger origin long GRB 211211A was a class (re-)defining event. A precursor was identified with a s separation from the main burst, as well as a claimed candidate quas…
