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…
