Scientific paper

In this paper, the author proposes a formation scenario of dwarf spheroidal galaxies (dSphs); part of dSphs form as a result of collision of dark matter (DM) halos which retain ISM (interstellar medium). First of all, a primordial dSph forms compact when collision of DM halos occurs. After the collision, the primordial dSph leaves a mass-radius relation among old stellar systems. This intermediate evolutionary phase finishes when the galactic wind occurs. Finally, it is re-virialized. Once this scenario is adopted, we explain the reason why large M/ L (mass-to-light ratio) is a result of galactic wind. Then, we conclude it is possible for part of dSphs to be remnants of DM halo collisions.
