Merging History as a Function of Halo Environment

  title={Merging History as a Function of Halo Environment},
  author={Andrey V. Kravtsov},
According to the hierarchical scenario, galaxies form via merging and accretion of small objects. Using N -body simulations, we study the frequency of merging events in the history of the halos. We find that at z ∼< 2 the merging rate of the overall halo population can be described by a simple power law (1+z) . The main emphasis of the paper is on the effects of environment of halos at the present epoch (z = 0). We find that the halos located inside clusters have formed earlier (∆z ≈ 1) than… CONTINUE READING
