Abstract
We use large volume, high resolution, N-body simulations of three different Lambda CDM models, with different clustering strengths, to generate dark-m atter halo merging histories. Over the reliable range of halo masses, rough ly galaxy groups to rich clusters of galaxies, we quantify the number densi ty of major mergers for two different time intervals and compare them with analytic predictions based on the extended Press-Schechter theory.
