Lossless compression of simulated radio interferometric visibilities
A. R. Offringa, R. J. van Weeren
Context. Processing radio interferometric data often requires storing forward-predicted model data. In direction-dependent calibration, these data may have a volume an order of mag…
A Very Rich Bimodal Galaxy Cluster Merger: RXC J0032.1+1808
David Wittman, Rodrigo Stancioli, Faik Bouhrik +3
The galaxy cluster RXC J0032.1+1808 has been well-studied with optical imaging and gravitational lensing mass maps, both of which reveal an elongated morphology in the north-south…
A Yin-Yang Galaxy Cluster Merger in Abell 1914 Revealed by XRISM
Annie Heinrich, Congyao Zhang, Irina Zhuravleva +4
Hierarchical mergers of galaxy clusters play a key role in converting gravitational energy into thermal and kinetic energy in the local universe. Understanding this process require…
Enhanced radio emission between a galaxy cluster pair
Andrea Botteon, Turgay Caglar, Sibel Döner +2
Interacting pairs of galaxy clusters offer a unique opportunity to study the properties of the gas residing in the intracluster bridge connecting them. As a consequence of the enco…
CHEX-MATE: New detections and properties of the radio diffuse emission in massive clusters with MeerKAT
M. Balboni, F. Gastaldello, A. Bonafede +18
Modern radio telescopes are revolutionising our understanding of non-thermal phenomena in galaxy clusters, collecting large samples of extended sources with unprecedented sensitivi…
The Crab Nebula at subarcsecond resolution with the International LOFAR Telescope
M. Arias, R. Timmerman, F. Sweijen +2
We present International LOw Frequency ARray (LOFAR) Telescope (ILT) observations of the Crab Nebula, the remnant of a core-collapse supernova explosion observed by astronomers in…
