We present preliminary results on galactic Dark Matter (DM), halo structure, and galaxy evolution. We show how during the first Gyr of the evolution of a 1010M⊙ dwarf elliptica feed-back from stars (SNæ~ and stellar winds) leads to an extended constant density isothermal core with radius of 0.15 the virial radius R200. We also present first results on galaxy merging as a possibile scenario to form ellipticals, studying in particular how the details of the merging evolution vary as a function of the mass ratio of the interacting galaxies.

Abstract

We present preliminary results on galactic Dark Matter (DM), halo structure, and galaxy evolution. We show how during the first Gyr of the evolution of a 1010M⊙ dwarf elliptica feed-back from stars (SNæ~ and stellar winds) leads to an extended constant density isothermal core with radius of 0.15 the virial radius R200. We also present first results on galaxy merging as a possibile scenario to form ellipticals, studying in particular how the details of the merging evolution vary as a function of the mass ratio of the interacting galaxies.
