Using a set of simulations in the ΛCDM cosmology, and the mass of intermediate X-Ray Active Galactic Nuclei (AGN) dark matter halos (DMH), we study the Halo Occupation Distribution (HOD) of their host DMH and compare with recent observations. We assume that intermediate X-Ray AGNs have been triggered by a major merger of sub-halos inside larger host halos. We find that the binary major merger HOD slope (α ≈ 0.8) do not seem to reproduce the observed HOD slope (α < 0.6) for these type of AGNs. Other mechanisms may be igniting these AGNs.
