The OTELO survey. III. Demography, morphology, IR luminosity and environment of AGN hosts

摘要: We take advantage of the capabilities OTELO survey to select and study AGN population in field. performed an analysis properties these objects, including their demography, morphology, IR luminosity. Focusing on H$\alpha$ emitters at $z \sim 0.4$, we also aim environments non-AGN galaxies that redshift. make use multiwavelength catalog objects field compiled by survey, unique terms minimum line flux equivalent width. The pseudo-spectra allow identification emission lines spectral classification sources. obtained a sample 72 AGNs OTELO, selected with four different methods optical, X-rays, mid-infrared bands. find using X-rays is most efficient way AGNs. An was order characterize its members. At up 26\% our are redshift, found identical non-AGNs, although they represent clustered group when compared passive star-forming galaxies. majority any redshift were classified as late-type galaxies, 16\% proportion irregulars. Another show signs interactions or mergers. Regarding infrared luminosity, able recover all luminous (LIRGs) $z\sim 1.6$. LIRGs ultra-luminous (ULIRGs) higher among population, ULIRGs fraction than LIRGs.
