• 論文の詳細を見る

• Dynamical collapse of the intracluster gas in clusters of galaxies is studied numerically by taking account of both the gavity of background galaxies and the self-gravity. The adiabatic case, the case with the thermal bremsstrahlung cooling and the case with both the heat conduction and thermal bremsstrahlung cooling and the case with both the heat conduction and thermal bremsstrahlung cooling have been calculated. In the first two cases, a hot plasma which is formed after the bounce reaches an equilibrium state if the initial density ρ_0 is lower than a certain critical value. In the last case, the gas secularly contracts. the results are compared with X-ray observation of the Coma cluster.
