The AzTEC mm-wavelength camera
AzTEC is a mm-wavelength bolometric camera utilizing 144 silicon nitride micromesh detectors. Here, we describe the AzTEC instrument architecture and its use as an astronomical instrument. We report on several performance metrics measured during a three-month observing campaign at the James Clerk Maxwell Telescope and conclude with our plans for AzTEC as a facility instrument on the Large Milli...
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 کاملAn AzTEC 1.1-mm survey for ULIRGs in the field of the Galaxy Cluster
We have undertaken a deep (σ ∼ 1.1 mJy) 1.1-mm survey of the z = 0.54 cluster MS 0451.6−0305 using the AzTEC camera on the James Clerk Maxwell Telescope. We detect 36 sources with signal-to-noise ratio (S/N) ≥ 3.5 in the central 0.10 deg2 and present the AzTEC map, catalogue and number counts. We identify counterparts to 18 sources (50 per cent) using radio, mid-infrared, Spitzer InfraRed Array...
متن کاملDeep 1.1 mm-wavelength imaging of the GOODS-S field by AzTEC/ASTE – II. Redshift distribution and nature of the submillimetre galaxy population
We report the results of the counterpart identification and a detailed analysis of the physical properties of the 48 sources discovered in our deep 1.1-mm wavelength imaging survey of the Great Observatories Origins Deep Survey-South (GOODS-S) field using the AzTEC instrument on the Atacama Submillimeter Telescope Experiment. One or more robust or tentative counterpart candidate is found for 27...
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...
