The Large Apex BOlometer Camera survey of the Extended Chandra Deep Field South. (2009)

Keywords : cosmology observations - galaxies: evolution - galaxies: high-redshift - galaxies: starburst - submillimeter; surveys

Abstract:We present a sensitive 870um survey of the Extended Chandra Deep Field South (ECDFS) combining 310hr of observing time with the Large Apex BOlometer Camera (LABOCA) on the APEX telescope. The LABOCA ECDFS Submillimetre Survey (LESS) covers the full 30'x30' field size of the ECDFS and has a uniform noise level of {sigma}_870um_~1.2mJy/beam. LESS is thus the largest contiguous deep submillimeter survey undertaken to date. The noise properties of our map show clear evidence that we are beginning to be affected by confusion noise. We present a catalog of 126 submillimeter galaxies (SMGs) detected with a significance level above 3.7{sigma}, at which level we expect five false detections given our map area of 1260arcmin^2^. ...(more)
Abstract: (hide)
Observations were carried out using the LABOCA on the APEX telescope at Llano de Chajnantor in Chile. The center wavelength of LABOCA is 870um (345GHz). The measured angular resolution of each beam is 19.2" FWHM. The observations were carried out between 2007 May and 2008 November. The mapping pattern was chosen to give a uniform coverage across a 30'x30' area centered at J033229.0-274847.0.
