Submm-bright X-ray absorbed QSOs at z~2: insights into the co-evolution of AGN and star-formation
We have assembled a sample of 5 X-ray-absorbed and submm-luminous type 1 QSOs
at which are simultaneously growing their central black holes
through accretion and forming stars copiously. We present here the analysis of
their rest-frame UV to submm Spectral Energy Distributions (SEDs), including
new Herschel data. Both AGN (direct and reprocessed) and Star Formation (SF)
emission are needed to model their SEDs. From the SEDs and their UV-optical
spectra we have estimated the masses of their black holes , their intrinsic AGN bolometric luminosities
, Eddington ratios
and bolometric corrections
. These values are common among optically and
X-ray-selected type 1 QSOs (except for RX~J1249), except for the bolometric
corrections, which are higher. These objects show very high far-infrared
luminosities (2 - 8) and Star Formation
Rates SFRy. From their and the shape of their
FIR-submm emission we have estimated star-forming dust masses of . We have found evidence of a tentative correlation between the
gas column densities of the ionized absorbers detected in X-ray (N)
and . Our computed black hole masses are amongst the most massive known.Comment: Accepted for publication in MNRAS, December 22, 2014, 17 pages, 5
