Abstract: Deep SCUBA surveys have uncovered a population of dustenshrouded star-forming galaxies at z ≈ 2. Using the ultra-deep 2Ms Chandra Deep Field-North survey, we recently showed that a large fraction of these systems are also undergoing intense black hole growth. Here we provide further constraints on the properties of the black holes in SCUBA galaxies using the virial black hole mass estimator. We show that typical SCUBA galaxies are likely to host black holes with MBH ≈ 107 − 108MSolar that are accreting at, or close to, the Eddington limit. These results provide qualitative support for our earlier conclusion that the growth of the black hole lags that of the host galaxy in these massive ultraluminous galaxies.
