AzTEC millimetre survey of the COSMOS field – I. Data reduction and source catalogue
We present a 1.1 mm wavelength imaging survey covering 0.3 deg2 in the COSMOS field. These data, obtained with the AzTEC continuum camera on the James Clerk Maxwell Telescope, were centred on a prominent large-scale structure overdensity which includes a rich X-ray cluster at z ≈ 0.73. A total of 50 mm-galaxy candidates, with a significance ranging from 3.5 to 8.5σ , are extracted from the cent...
متن کاملAzTEC millimetre survey of the COSMOS field – III. Source catalogue over 0.72 deg2 and plausible boosting by large-scale structure
We present a 0.72 deg2 contiguous 1.1-mm survey in the central area of the Cosmological Evolution Survey field carried out to a 1σ ≈ 1.26 mJy beam−1 depth with the AzTEC camera mounted on the 10-m Atacama Submillimeter Telescope Experiment. We have uncovered 189 candidate sources at a signal-to-noise ratio (S/N) ≥ 3.5, out of which 129, with S/N ≥ 4, can be considered to have little chance of b...
متن کاملAn AzTEC 1.1 mm survey of the GOODS-N field - I. Maps, catalogue and source statistics
We have conducted a deep and uniform 1.1mm survey of the GOODS-N field with AzTEC on the James Clerk Maxwell Telescope (JCMT). Here we present the first results from this survey including maps, the source catalogue, and 1.1mm numbercounts. The results presented here were obtained from a 245 arcmin region with near uniform coverage to a depth of 0.96–1.16mJy beam. Our robust catalogue contains 2...
متن کاملDeep 1.1?mm?wavelength imaging of the GOODS?S field by AzTEC/ASTE ? I. Source catalogue and number counts
We present the first results from a 1.1 mm confusion-limited map of the Great Observatories Origins Deep Survey-South (GOODS-S) taken with the AzTEC camera on the Atacama Submillimeter Telescope Experiment. We imaged a 270 arcmin2 field to a 1σ depth of 0.48–0.73 mJy beam−1, making this one of the deepest blank-field surveys at mm-wavelengths ever achieved. Although by traditional standards our...
متن کامل(Sub)millimetre interferometric imaging of a sample of COSMOS/AzTEC submillimetre galaxies – I. Multiwavelength identifications and redshift distribution
We used the Plateau de Bure Interferometer (PdBI) to map a sample of 15 submillimetre galaxies (SMGs) in the COSMOS field at the wavelength of 1.3 mm. The target SMGs were originally discovered in the James Clerk Maxwell Telescope (JCMT)/AzTEC 1.1 mm continuum survey at S/N1.1 mm = 4 − 4.5. This paper presents, for the first time, interferometric millimetre-wavelength observations of these sour...
