A JWST redshift for the host galaxy of EP250207b of z=3.2: a collapsar origin is viable
Agnes P. C. van Hoof, Peter G. Jonker, Andrew J. Levan +27
We present James Webb Space Telescope (JWST) and Hubble Space Telescope (HST) observations of the field of the fast X-ray transient (FXT) detected by Einstein Probe, EP250207b, to…
Can GRB 250702B be explained as the tidal disruption of a white dwarf by an intermediate mass black hole? Yes
Rob AJ Eyles-Ferris, Andrew King, Rhaana LC Starling +11
GRB 250702B is a unique astrophysical transient characterised by its nature as a repeating gamma-ray trigger. Its properties include possible periodicity in its gamma-ray light cur…
GRBs and Relativistic Transients in the 2040s
Nikhil Sarin, Andrew Levan, Nial Tanvir +9
Relativistic transients such as gamma-ray bursts (GRBs), jetted tidal disruption events, luminous fast blue optical transients, and fast X-ray transients, represent the brightest e…
Observatory Science with eXTP
Ping Zhou, Jirong Mao, Liang Zhang +97
Scheduled for launch in 2030, the enhanced X-ray Timing and Polarization (eXTP) telescope is a Chinese space-based mission aimed at studying extreme conditions and phenomena in ast…
The Heavy Element Enrichment History of the Universe from Neutron Star Mergers with Habitable Worlds Observatory
Eric Burns, Jennifer Andrews, Robert Szabo +23
Understanding where elements were formed has been a key goal in astrophysics for nearly a century, with answers involving cosmology, stellar burning, and cosmic explosions. Since 1…
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…
