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 +24
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…
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…
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…
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…
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 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…
Multi-messenger-Athena Synergy White Paper
L. Piro, M. Ahlers, A. Coleiro +30
In this paper we explore the scientific synergies between Athena and some of the key multi-messenger facilities that should be operative concurrently with Athena. These facilities…
The Transient High-Energy Sky and Early Universe Surveyor (THESEUS)
L. Amati, E. Bozzo, P. O'Brien +1
The Transient High-Energy Sky and Early Universe Surveyor (THESEUS) is a mission concept developed in the last years by a large European consortium and currently under study by the…
Deeper H.E.S.S. observations of Vela Junior (RX J0852.04622): Morphology studies and resolved spectroscopy
H. E. S. S. Collaboration, H. Abdalla, A. Abramowski +260
Aims. We study gamma-ray emission from the shell-type supernova remnant (SNR) RX J0852.04622 to better characterize its spectral properties and its distribution over the SNR. Me…
Are GRBs the same at high and low redshift?
O. M. Littlejohns, N. R. Tanvir, R. Willingale +3
Due to their highly luminous nature, gamma-ray bursts (GRBs) are useful tools in studying the early Universe (up to z = 10). We consider whether the available subset of Swift high…
Spectral evolution and the onset of the X-ray GRB afterglow
P. A. Evans, J. P. Osborne, R. Willingale +1
Based on light curves from the Swift Burst Analyser, we investigate whether a `dip' feature commonly seen in the early-time hardness ratios of Swift-XRT data could arise from the j…
The unusual X-ray emission of the short Swift GRB 090515: Evidence for the formation of a magnetar?
A. Rowlinson, P. T. O'Brien, N. R. Tanvir +16
The majority of short gamma-ray bursts (SGRBs) are thought to originate from the merger of compact binary systems collapsing directly to form a black hole. However, it has been pro…
Can X-ray emission powered by a spinning-down magnetar explain some GRB light curve features?
N. Lyons, P. T. O'Brien, B. Zhang +3
Long duration gamma-ray bursts (GRBs) are thought to be produced by the core-collapse of a rapidly-rotating massive star. This event generates a highly relativistic jet and prompt…
The multiwavelength afterglow of GRB 050721: a puzzling rebrightening seen in the optical but not in the X-ray
L. A. Antonelli, V. Testa, P. Romano +27
Context. GRB050721 was detected by Swift and promptly followed-up, in the X-ray by Swift itself and, in the optical band, by the VLT operated, for the first time, in rapid response…
