Abstract:
We present the first results from a 1.1mm 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 270arcmin2 field to a 1σ depth of 0.48-0.73mJy/beam,
making this one of the deepest blank-field surveys at mm-wavelengths
ever achieved. Although by traditional standards our GOODS-S map is
extremely confused due to a sea of faint underlying sources, we
demonstrate through simulations that our source identification and
number counts analyses are robust, and the techniques discussed in
this paper are relevant for other deeply confused surveys. We find a
total of 41 dusty starburst galaxies with signal-to-noise ratios
S/N≥3.5 within this uniformly covered region, where only two are
expected to be false detections, and an additional seven robust source
candidates located in the noisier (1σ∼1mJy/beam) outer region of
the map.
Description:
We imaged a 26x20arcmin2 field centred at 03:32:30-27:8:20 (J2000)
at 1.1mm using AzTEC on the ASTE.

Note (1): The first 41 sources (AzTEC/GS1-AzTEC/GS40) are detected with
S/N≥3.5 within the uniform coverage region of the AzTEC/GOODS-S map,
where two are expected to be false positives. The seven additional
S/N≥4.5 sources (AzTEC/GS41-AzTEC/GS47) are located outside the
uniform coverage region.
