Old Galaxies at High Redshift and the Cosmological Constant
In a recent striking discovery, Dunlop et al [1] observed a galaxy at redshift z=1.55 with an estimated age of 3.5 Gyr. This is incompatible with age estimates for a flat matter dominated universe unless the Hubble constant is less than 45kmsMpc. While both an open universe, and a universe with a cosmological constant alleviate this problem, I argue here that this result favors a non-zero cosmo...

15 صفحه اولCo and Near-infrared Observations of High-redshift Submillimeter Galaxies
I discuss our ongoing Owens Valley Millimeter Array observations and Keck nearinfrared wavelength observations of the high-redshift sub-mm population of galaxies. These observations are important for our understanding of the distant universe since the sub-mm population accounts for a large fraction of the extragalactic background at mm/sub-mm wavelengths and contributes significantly to the tot...
متن کاملHigh resolution CO imaging of high redshift QSO host galaxies
We review recent high-resolution CO observations of distant QSOs obtained at the Very Large Array. The aim of these observations is to resolve the molecular gas distribution in these extreme objects both spatially and in velocity space. They provide unique information regarding the small-scale distribution, the extent, and the brightness temperatures of the molecular gas in these early systems....
متن کاملHerschel-ATLAS: the angular correlation function of submillimetre galaxies at high and low redshift
We present measurements of the angular correlation function of galaxies selected from the first field of the H-ATLAS survey. Careful removal of the background from galactic cirrus is essential, and currently dominates the uncertainty in our measurements. For our 250 μm-selected sample we detect no significant clustering, consistent with the expectation that the 250 μm-selected sources are mostl...
