Formation and Evolution of Galactic Halos in Clusters of Galaxies
Abstract
Description
We investigate effects of time evolution of a rich cluster of galaxies on its member galactic halos in the standard cold dark matter (SCDM) universe using high resolution N-body simulations. We identify several hundred galactic halos within virial radius of our simulated cluster. We also find that a large number of halos have been tidally disrupted at z = 0. Therefore we improve a method of deriving merging history trees of galaxies taking account of tidally stripped galaxies.
