Gas equilibrium in the gravitational field of cD-galaktik

The possibility to apply the solutions of hydrostatic and energy equilibrium equations for the description of gas distribution in cD galaxy's gravity field has been investigated. It has been shown that the energy equilibrium condition without the energy fluxes are most probably unfulfilled. The radiation losses in the center of cD galaxies are then balanced by the electron thermal conductivity and by the energy fluxes from the hotter outer regions of cD-galaxies
