Mid-IR-selected Quasars in the Spitzer First Look Survey

Abstract

We present an investigation of the spectral energy distribution of mid-IR-selected quasars from the Spitzer First Look and SWIRE surveys. We explore a suite of clumpy torus models from Nenkova et al. (2002) to see how well they fit the types of objects we find. For about one-third of our objects these models underestimate the amount of observed 70 micron emission. We constrain the contribution and rough population age of the AGN hosts and use radio, 70 and 24 micron data to characterize the star-forming properties of these objects.
