An omnipresent feature of the multi-phase``cosmic web''is that warm/hot (> $10^ 5$ K)
ionized gas pervades it. This gas constitutes a relevant contribution to the overall universal …

Aims. Recent X-ray and Sunyaev–Zeldovich (SZ) observations have detected thermal
emission between early-stage merging galaxy clusters. The main purpose of this work is to …

Improved polarization measurements at frequencies below 70 GHz with degree-level
angular resolution are crucial for advancing our understanding of the Galactic synchrotron …

Galaxy cluster mergers are natural consequences of structure formation in the Universe.
Such events involve the dissipation of a large amount of energy (∼ 10 63 erg) during the …

Aims. Recent low-frequency radio observations at 140 MHz discovered a bridge of diffuse
emission with a length of 3 Mpc that connects the galaxy clusters Abell 0399 and Abell 0401 …

According to CMB measurements, baryonic matter constitutes about $5\% $ of the mass-
energy density of the universe. A significant population of these baryons, for a long time …

Abstract ACT-CL J0034. 4+ 0225 is a previously unrecognized merging galaxy cluster at z=
0.38588±0.00068. Our primary evidence is provided by a 21 ks Chandra image that shows …

Cosmic rays (CRs) in the shape of relativistic protons and electrons are the source of non-
thermal radiation in a plethora of astrophysical systems. Their emission provides insights …
