Abstract
Using data from SDSS, UKIDSS, and WISE, we investigate the properties of the high-frequency cutoff to the infrared emission in similar or equal to 5000 carefully selected luminous (L-bol similar to 10(47)) type 1 quasars. The strength of similar or equal to 2 mu m emission, corresponding to emission from the hottest (T > 1200 K) dust in the sublimation zone surrounding the central continuum source, is observed to correlate with the blueshift of the CIV lambda 1550 emission line. We therefore find that objects with stronger signatures of nuclear outflows tend to have a larger covering fraction of sublimation-temperature dust. When controlling for the observed outflow strength, the hot dust covering fraction does not vary significantly across our sample as a function of luminosity, black hole mass, or Eddington fraction. The correlation between the hot dust and the CIV line blueshifts, together with the lack of correlation between the hot dust and other parameters, therefore provides evidence of a link between the properties of the broad emission line region and the infrared-emitting dusty regions in quasars.
