Tamayo Física, Astronomía y Matemáticas halos active methods Galaxies galaxies Motivated by the shape of the halo occupation distribution (HOD) of Xray selected AGNs in the COSMOS field recently inferred by Allevato et al., we investigated the HOD properties of moderate X-ray luminosity active galactic nuclei (mXAGNs) using a simple model based on the merging activity between dark matter halos (DMHs) in a ΛCDM cosmology. The HODs and number densities of the simulated mXAGNs at z = 0 .5, under the above scenarios were compared with the results of Allevato et al. We found that the simulated HODs of major and minor mergers, and the observed HODs of mXAGNs are consistent. Our main result is that minor mergers, contrary to what one might expect, can play an important role in the activity of mAGNs. 2016 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57146052002 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.1 Vol.52 |
