SWIRE/SDSS quasars. II. Type 2 AGN

It focuses on low-luminosity, low-redshift (z<=0.25) AGN selected among emission line galaxies in the overlapping regions between Spitzer Wide-area Infrared Extragalactic Survey (SWIRE) and Sloan Digital Sky Survey Data Release 4 as well as X-ray, radio and mid-infrared selected type 2 AGN samples from the literature.

The available multiband photometry covers the spectral range from the u band up to 160um. Using a standard chi^2^ minimization, the observed SED of each object is fit to a set of multicomponent models comprising a stellar component, a high optical depth (tau_9.7_>=1.0) torus and cold emission from a starburst (SB). The torus components assigned to the majority of the objects were those of the highest optical depth of our grid of models (tau_9.7_=10.0).
