We identify and characterize a population of luminous, dust-poor quasars at 0 < z < 5 that is photometrically similar to objects previously found at z > 6. This class of active galactic nuclei is known to show little IR emission from dusty structure, but it is poorly understood in terms of number evolution and dependence on physical quantities. To better understand the properties of these quasars, we compile a rest-frame UV to IR library of 41,000 optically selected type 1 quasars with Lbol…

Observations of polarized light interior to the dust-emitting region that enable the revealed spectra show that the near-infrared disk spectrum is indeed as blue as predicted, indicating that, at least for the outer near-Infrared-emmitting radii, the standard picture of the locally heated disk is approximately correct.
