摘要: We present a new backward evolution model for galaxies and active galactic nuclei (AGNs) in the infrared (IR). What is this separate study of evolutionary properties different IR populations (i.e. spiral galaxies, starburst low-luminosity AGNs, ‘unobscured’ type 1 AGNs ‘obscured’ 2 AGNs) defined through detailed analysis spectral energy distributions (SEDs) large samples IR-selected sources. The parameters have been constrained by means all available observables from surveys mid- far-IR (source counts, redshift luminosity distributions, functions). By decomposing SEDs representative three AGN classes into distinct components (a stellar component emitting most its power optical/near-IR, an due to hot dust heated central black hole peaking mid-IR, dominating spectrum), we disentangled contribution monochromatic total emitted considered our that star formation activity. then obtained estimate density [and (SFD) produced galaxies] first ever mass accretion (BHAR) IR. derived BHAR agreement with estimates X-rays, though values derive are slightly higher than X-ray ones. Finally, simulated source SFD expect obtain future cosmological mid-/far-IR will be performed JWST-MIRI SPICA-SAFARI. Outputs online.1
