Abstract

We present near-IR spectroscopy of a sample of luminous (Lbol >10^14 Lsun), sub-millimeter-detected, dusty (M_dust~10^9 Msun), radio-quiet QSOs at z~2. We measure the redshift, width, and luminosity of the Halpha line, and the continuum luminosity near Ha. The Halpha emission line was strongly detected in all sources. Two components -- a very broad (>~5000 km/s) Gaussian and an intermediate-width (>~1500 km/s) Gaussian, were required to fit the Halpha profile of all observed QSOs. Narrow (
