Title: Beyond the Tip of the Iceberg: Finding Red Quasars in Deep Infrared Imaging over the 115 deg2 of Stripe 82

Abstract: We propose to obtain near-infrared spectra on a sample of radio-quiet dust-reddened quasar candidates selected from deep Spitzer observations over SDSS Stripe 82. These sources are the radio-quiet analogs to previously-identified red quasars selected by matching the FIRST survey with near-infrared surveys such as 2MASS and UKIDSS (F2M and UKFS). Detailed studies of their properties have shown that red quasars are accreting at very high rates and exhibit broad absorption lines associated with outflows and feedback. Their properties are consistent with buried quasars expelling their dusty shrouds in an an evolutionary phase predicted by merger-driven co-evolution models. When corrected for extinction, red quasars are the most intrinsically luminous objects in the Universe. However, recent lines of evidence suggest that radio emission may be linked to AGN reddening and merging hosts and may not only trigger star formation and SMBH growth, but may also be responsible for launching jets. This study will allow us to test this hypothesis by assembling a radio-independent sample of red quasars whose properties can be compared with the radio-selected sample.
