The difficulty in constraining this population leads to high uncertainties in cosmic X-ray background and galaxy evolution models. Using an SDSS-WISE cross-match, we target infrared luminous AGN ($W1-W2$ > 0.8, and monochromatic rest-frame luminosity above $\\lambda L_{\\lambda}$(12$\\mu$m) $\\approx$ 3 $\\times$ 10$^{44}$ erg s$^{-1}$), but with passive galaxy-like optical spectra (Optically Quiescent Quasars; OQQs).
