摘要: Non-thermal motions in the intra-cluster medium (ICM) are believed to play a non-negligible role pressure support total gravitating mass of galaxy clusters. Future high-precision X-ray missions will allow us directly detect signature these from highly resolved spectra ICM. With this perspective, we present here study on set clusters extracted cosmological hydrodynamical simulation, for which simulated observations and characterized them via non-thermal velocity amplitude We have applied virtual telescope PHOX generate mock estimated an observational fashion global properties. included ICM as additional parameter further identify non-regular In particular, influence internal gas location LX-T plane was investigated found that objects with largest amount average higher luminosities.
