Measuring the hot ICM velocity structure function using XMM-Newton observations

Efrain Gatuzz, R. Mohapatra, C. Federrath +4

It has been shown that the gas velocities within the intracluster medium (ICM) can be measured by applying novel XMM-Newton EPIC-pn energy scale calibration, which uses instrumenta…

Extreme Variability in a Long Duration Gamma-ray Burst Associated with a Kilonova

P. Veres, P. N. Bhat, E. Burns +19

The recent discovery of a kilonova from the long duration gamma-ray burst, GRB 211211A, challenges classification schemes based on temporal information alone. Gamma-ray properties…

Deciphering the unusual stellar progenitor of GRB 210704A

R. L. Becerra, E. Troja, A. M. Watson +16

GRB~210704A is a burst of intermediate duration (~s) followed by a fading afterglow and an optical excess that peaked about 7 days after the explosion. Its propert…

A Model of EUV Emission from Clusters of Galaxies

Richard Lieu, Chun-Hui Shi

With tantalizing evidence of the recent e-Rosita mission, re-discovering very soft X-rays and EUV radiation from a cluster of galaxies or its environment, the question of the origi…

Intergalactic magnetic field studies by means of -ray emission from GRB 190114C

Paolo Da Vela, Guillem Martí-Devesa, Francesco Gabriele Saturni +3

The presence of delayed GeV emission after a strong transient, such as a GRB (Gamma-Ray Burst), in the VHE (Very-High Energy, GeV) band can be the signature of a non-zero m…
