On the coherent rotation of diffuse matter in numerical simulations of galaxy clusters

Understand

We present a study on the coherent rotation of the intracluster medium and dark matter components of simulated galaxy clusters extracted from a volume-limited sample of the MUSIC project.

• The set is re-simulated with three different recipes for the gas physics: $(i)$ non-radiative, $(ii)$ radiative without AGN feedback, and $(iii)$ radiative with AGN feedback.
• Our analysis is based on the 146 most massive clusters identified as relaxed, 57 per cent of the total sample.
• We classify these objects as rotating and non-rotating according to the gas spin parameter, a quantity that can be related to cluster observations.
