Radio Halos in Galaxy Clusters as unveiled by the SKA telescope
R. Cassano, G. Di Gennaro, V. Cuciti +24
Giant radio halos (RHs) are diffuse, Mpc-scale synchrotron sources observed in a growing fraction of galaxy clusters. They trace relativistic particles and magnetic fields in the i…
The Large-Scale Structure of the Universe through the SKA lenses
Virginia Cuciti, Surajit Paul, Viral Parekh +11
The large-scale distribution of galaxies in the Universe forms an intricate, interconnected network known as the cosmic web. Cosmological simulations within the standard Lambda-CDM…
The Cosmic Ray Life Cycle in Galaxy Clusters
Francesco de Gasperin, Marcus Brüggen, Henrik Edler +3
Within the cosmic web, gravitational energy, linked to the formation and growth of the Universe's largest structures and the activity of active galactic nuclei (AGN), is converted…
AGN Jets from Formation to Dissipation
A. -K. Baczko, Eleni Vardoulaki, Etienne Bonnassieux +26
Active Galactic Nuclei (AGN) are among the most energetic phenomena in the Universe, capable of launching powerful relativistic jets that extend from sub-parsec to megaparsec scale…
Bulk and turbulent gas motions in the interacting galaxy cluster Abell 3395 South observed with XRISM
Naomi Ota, Angie Veronica, Jakob Dietl +8
We investigate the gas motions in the core region of the Abell~3395 South subcluster (A3395S) using high-resolution X-ray spectroscopy with XRISM/Resolve. By analyzing the Fe~XXV H…
Inverse energy transfer in decaying MHD turbulence: A shell-to-shell analysis
Lenard Kasselmann, Philipp Grete, Pranjal Trivedi +2
In decaying magnetohydrodynamic turbulence, energy can be transported from small to large scales, known as inverse transfer. We explore the mechanism behind this phenomenon using s…
