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…

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]…

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…

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…

The fast X-ray transient EP240315a: a z ~ 5 gamma-ray burst in a Lyman continuum leaking galaxy

Andrew J. Levan, Peter G. Jonker, Andrea Saccardi +73

The nature of the minute-to-hour long Fast X-ray Transients (FXTs) localised by telescopes such as Chandra, Swift, and XMM-Newton remains mysterious, with numerous models suggested…
