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…
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…
Is the Sunyaev-Zeldovich effect responsible for the observed steepening in the spectrum of the Coma radio halo ?
G. Brunetti, L. Rudnick, R. Cassano +3
The spectrum of the radio halo in the Coma cluster is measured over almost two decades in frequency. The current radio data show a steepening of the spectrum at higher frequencies,…
Revisiting scaling relations for giant radio halos in galaxy clusters
R. Cassano, S. Ettori, G. Brunetti +6
Many galaxy clusters host Megaparsec-scale radio halos, generated by ultrarelativistic electrons in the magnetized intracluster medium. Correlations between the power of radio halo…
