Type 2 AGN host galaxies in the Chandra-COSMOS Legacy Survey: No evidence of AGN-driven Quenching

We investigate the star formation properties of a large sample of similar to 2300 X-ray-selected Type 2 Active Galactic Nuclei (AGNs) host galaxies out to z similar to 3 in the Chandra COSMOS Legacy Survey in order to understand the connection between the star formation and nuclear activity. Making use of the existing multi-wavelength photometric data available in the COSMOS field, we perform a multi-component modeling from far-infrared to near-ultraviolet using a nuclear dust torus model, a stellar population model and a starburst model of the spectral energy distributions (SEDs). Through detailed analyses of SEDs, we derive the stellar masses and the star formation rates (SFRs) of Type 2 AGN host galaxies. The stellar mass of our sample is in the range of 9 3), and grow slowly through secular fueling processes hosting moderate-luminosity AGNs.NASA GO3-14150C GO3-14150B GO5-16150A Swiss National Science Foundation PP00P2_138979 PP00P2_166159 European Union 60941
