CAA Seminar (04.18/2019)Turbulence and non-thermal pressure in the intracluster ’stratosphere’

Description

DoA Small Seminar Room,Thursday 18 Apr, 4:00pm-5:00pm

Speaker: Xun Shi (SWIFAR)


Abstract: Galaxy clusters are promising probes for cosmology, and yet, their astrophysical complexity leads to significant systematical bias as shown by the Planck CMB-cluster discrepancy. Turbulence in the intracluster medium (ICM) and the corresponding non-thermal pressure are a central piece of the astrophysical complexity that has not been well-explored. I will present recent developments in this area, and in particular, discuss a largely neglected effect - the influence of ICM density stratification on turbulence dissipation, as well as its role in shaping the typical radial distribution of ICM turbulence.
