AzTEC Half Square Degree Survey of the SHADES Fields -- I. Maps, Catalogues, and Source Counts
(2009-07-06)
We present the first results from the largest deep extragalactic millimetre-wavelength survey undertaken to date. These results are derived from maps covering over 0.7 deg^2, made at 1.1mm, using the AzTEC continuum camera ...
A LABOCA survey of the Extended Chandra Deep Field South - submillimeter properties of near-IR selected galaxies
(2009-03-31)
Using the 330hr ESO-MPG 870-micron survey of the Extended Chandra Deep Field South (ECDF-S) obtained with the Large Apex BOlometer CAmera (LABOCA) on the Atacama Pathfinder EXperiment (APEX), we have carried out a stacking ...
A Search for Neutral Carbon towards two z=4.05 Submillimetre Galaxies, GN20 and GN20.2
(2009-08-26)
Using the IRAM Plateau-de-Bure Interferometer (PdBI) we have searched for the upper fine structure line of neutral carbon (CI(2->1), nu_rest = 809 GHz) and 12CO(J=7->6) (nu_rest=806GHz) towards the submillimetre galaxies ...
Do submillimeter galaxies really trace the most massive dark matter halos? Discovery of a high-z cluster in a highly active phase of evolution
(2009-01-20)
We present detailed observations of a z~1.99 cluster of submillimeter galaxies (SMGs), discovered as the strongest redshift spike in our entire survey of ~100 SMGs across 800 square arcmin. It is the largest blank-field ...
High-resolution CO and radio imaging of ULIRGs: extended CO structures, and implications for the universal star formation law
(2009-12-09)
We present high spatial resolution (0.4", ~3.5 kpc) PdBI interferometric data on three ultra-luminous infrared galaxies (ULIRGs) at z~2: two submillimetre galaxies and one submillimetre faint star forming radio galaxy. The ...
The Chandra Deep Protocluster Survey: Lyα Blobs are powered by heating, not cooling
(2009-07-20)
We present the results of a 400ks Chandra survey of 29 extended Ly-alpha emitting nebulae (Ly-alpha Blobs, LABs) in the z=3.09 proto-cluster in the SSA22 field. We detect luminous X-ray counterparts in five LABs, implying ...
