On the interpretation of XRISM X-ray measurements of turbulence in the intracluster medium: a comparison with cosmological simulations
F. Vazza, G. Brunetti
We investigate whether the properties of turbulent gas motions recently measured via X-ray spectroscopy in the Coma cluster of galaxies by XRISM are in tension with the turbulent p…
Investigating the intracluster medium viscosity using the tails of GASP jellyfish galaxies
Alessandro Ignesti, Gianfranco Brunetti, Marco Gullieuszik +13
The microphysics of the intracluster medium (ICM) in galaxy clusters is still poorly understood. Observational evidence suggests that the effective viscosity is suppressed by plasm…
Cosmological simulations of the generation of cluster-scale radio emission from turbulent re-acceleration
Luca Beduzzi, Franco Vazza, Virginia Cuciti +3
Context. The recent discovery of so-called mega radio halos as a new class of diffuse, steep-spectrum radio sources in clusters of galaxies has raised questions about the origin an…
Efficiency of turbulent reacceleration by solenoidal turbulence and its application to the origin of radio mega halos in cluster outskirts
Kosuke Nishiwaki, Gianfranco Brunetti, Franco Vazza +1
Recent radio observations with Low-Frequency Array (LOFAR) discovered diffuse emission extending beyond the scale of classical radio halos. The presence of such mega halos indicate…
Abell 1430: A merging cluster with exceptional diffuse radio emission
M. Hoeft, C. Dumba, A. Drabent +16
Diffuse radio emission has been found in many galaxy clusters, predominantly in massive systems which are in the state of merging. The radio emission can usually be classified as r…
Dynamical evolution of magnetic fields in the intracluster medium
Paola Domínguez-Fernández, Franco Vazza, Marcus Brüggen +1
We investigate the evolution of magnetic fields in galaxy clusters starting from constant primordial fields using highly resolved () cosmological MHD simulation…
