Thermal Evaporation of Gas from X-ray Clusters
A fraction of the thermal protons in the outer envelope of an X-ray cluster have velocities that exceed the local escape speed from the cluster gravitational potential. The Coulomb mean-freepath of these protons is larger than the virial radius of the cluster at temperatures & 2.5keV. The resulting leakage of suprathermal particles generates a collisionless shock in neighboring voids and fills ...
متن کاملX-ray emission from clusters of galaxies
Clusters of galaxies are gravitationally bound configurations containing typically hundreds of galaxies in a region about 10 cm in size. They range from irregular clusters, with strong subclustering, no strong central concentration, and mainly spiral galaxies, to regular clusters, with smooth and centrally condensed galaxy distributions containing few spiral galaxies. Observations of these clus...
متن کاملX{ray emission from Clusters of Galaxies
In the last eight years, the Chandra and XMM–Newton satellites changed significantly our view of X–ray clusters of galaxies. In particular, several complex phenomena have been directly observed: interactions between cluster galaxies and the Intra Cluster Medium (ICM), cold fronts in the ICM, hot bubbles due to relativistic jets from radio loud AGN, the lack of cold gas in “cool–cores”, and non–...
متن کاملX-ray Emission from Clusters of Galaxies
We present a summary of X-ray spectral observations of 30 clusters of galaxies from HEAO-1. There exists strong correlations between X-ray luminosity, Lx , and temperature kT in the form L xaT2 ' 3 . This result combined with the Lx vs central galaxy density relation and the virial theorem indicates that the core radius of the gas should be roughly independent of Lx or KT and that more luminous...
متن کاملAre Large X–ray Clusters at Thermal Equilibrium?
We simulate the formation of a large X–ray cluster using a fully 3D hydrodynamical code coupled to a Particle–Mesh scheme which models the dark matter component. We focus on a possible decoupling between electrons and ions temperatures. We then solve the energy transfer equations between electrons, ions and neutrals without assuming thermal equilibrium between the three gases (Te 6= Ti 6= Tn). ...
