Abstract: | Numerical simulations of the dynamical evolution of a galaxy cluster in the framework of the N-body problem taking into account dark matter are presented. These simulations are aimed at studying the role of intergalactic
gas in the cluster (the ICM) in the formation of a central, supermassive cD galaxy. The numerical models indicate that deceleration
of the galaxies by intergalactic gas supports the observed high temperature of this gas, and accelerates the formation of
a supermassive cD galaxy in the cluster core. The accretion of interstellar gas by the cluster core can support a high accretion
rate by the central, supermassive black hole associated with the nucleus of the cD galaxy. As a result, this nucleus harbors
a bright quasar. The mass of the black hole can grow with time to values 1010
M
⊙, as are observed for the brightest quasars. |
