Fastest or Significant: A Systematic Framework for Validating Global Minimum Variability Timescale Measurements of Gamma-ray Bursts

S. Bala, P. Veres, A. Goldstein +3

The minimum variability timescale (MVT) is a key observable used to probe the central engines of Gamma-Ray Bursts (GRBs) by constraining the emission region size and the outflow Lo…

Constraints on the intergalactic magnetic field from Fermi-LAT observations of GRB 221009A

Lea Burmeister, Paolo Da Vela, Francesco Longo +5

A cosmological origin of the magnetic fields in large scale structures of the Universe would require a non-negligible magnetic field in cosmic voids, which, however, remains undete…

From Observations to Simulations: A Neural-Network Approach to Intracluster Medium Kinematics

E. Gatuzz, J. ZuHone, J. S. Sanders +4

We present a systematic comparison between {\it XMM-Newton} velocity maps of the Virgo, Centaurus, Ophiuchus and A3266 clusters and synthetic velocity maps generated from the Illus…

The Quiescent Merging Nature of the Coma Cluster Revealed by ICM Velocity Structure

E. Gatuzz, J. Sanders, A. Liu +4

The hot gas permeating galaxy clusters-the intracluster medium (ICM)-is a key tracer of their assembly history and internal dynamics. Understanding the motion of this gas provides…

From Rare Events to a Population: Discovering Overlooked Extragalactic Magnetar Giant Flare Candidates in Archival Fermi Gamma-ray Burst Monitor Data

Aaron C. Trigg, Eric Burns, Michela Negro +16

Magnetar giant flares (MGFs) are rare, extremely bright bursts of gamma-rays from highly magnetized neutron stars. These events are challenging to identify because, at extragalacti…

GRB 250702B: Discovery of a Gamma-Ray Burst from a Black Hole Falling into a Star

Eliza Neights, Eric Burns, Chris L. Fryer +52

Gamma-ray bursts are the most luminous electromagnetic events in the universe. Their prompt gamma-ray emission has typical durations between a fraction of a second and several minu…

GRB 241105A: A test case for GRB classification and rapid r-process nucleosynthesis channels

Dimple, B. P. Gompertz, A. J. Levan +85

Gamma-ray bursts (GRBs) offer a powerful window to probe the progenitor systems responsible for the formation of heavy elements through the rapid neutron capture (r-) process, than…

NuSTAR Observations of the Galaxy Cluster Abell 3667

Mohammad S. Mirakhor, Stephen A. Walker

We present an analysis of the hard X-ray emission from the central region of Abell 3667 using deep NuSTAR observations. While previous studies on the nature of the hard X-ray exces…

The bulk motion of gas in the core of the Centaurus galaxy cluster

XRISM collaboration

Galaxy clusters, the largest gravitationally bound structures in the Universe, contain vast amounts of dark matter, galaxies, and hot ionised gas known as the intracluster medium (…
