Weighing the Black Holes in z~2 Submillimeter-Emitting Galaxies Hosting Active Galactic Nuclei
(2008-05-01)
We place direct observational constraints on the black-hole masses of the cosmologically important z~2 submillimeter-emitting galaxy (SMG; f850>4mJy) population, and use measured host-galaxy masses to explore their ...
Interferometric CO Observations of submillimeter-faint, radio-selected starburst galaxies at z~2
(2008-12-20)
High-redshift, dust-obscured galaxies -- selected to be luminous in the radio but relatively faint at 850um -- appear to represent a different population from the ultra-luminous submillimeter- (submm-) bright population. ...
The SCUBA Half Degree Extragalactic Survey (SHADES) - VII. Optical/IR photometry and stellar masses of sub-millimeter galaxies
(2008-05)
We present estimates of the photometric redshifts, stellar masses and star formation histories of sources in the SCUBA HAlf Degree Extragalactic Survey (SHADES). This paper describes the 60 SCUBA sources detected in the ...
Submillimeter Galaxies at z 2: Evidence for Major Mergers & Constraints on Lifetimes, IMF and CO-H2 Conversion Factor
(2008-06-10)
We report sub-arcsecond resolution IRAM PdBI millimeter CO interferometry of four z~2 submillimeter galaxies (SMGs), and sensitive CO (3-2) flux limits toward three z 2 UV-/optically selected star forming galaxies. The new ...
