X-UDS the Chandra Legacy Survey of the UKIDSS Ultra Deep Survey field. (2018)

Keywords : galaxies active ; galaxies: nuclei ; surveys ; X-rays: galaxies

Abstract:We present the X-UDS survey, a set of wide and deep Chandra observations of the Subaru-XMM Deep/UKIDSS Ultra Deep Survey (SXDS/UDS) field. The survey consists of 25 observations that cover a total area of 0.33deg^2^. The observations are combined to provide a nominal depth of ~600ks in the central 100arcmin^2^ region of the field that has been imaged with Hubble/WFC3 by the CANDELS survey and ~200ks in the remainder of the field. In this paper, we outline the survey's scientific goals, describe our observing strategy, and detail our data reduction and point source detection algorithms. Our analysis has resulted in a total of 868 band-merged point sources detected with a false-positive Poisson probability of <1x10^-4^. In addition, we ...(more)

The X-UDS observations were carried out with Chandra's Advanced CCD Imaging Spectrometer (ACIS) in the time period 2015 July 6 to 2015 October 4. The observations consist of 25 pointing positions that cover a total area of roughly 35'x25' in size. A summary of the observational parameters of the X-UDS exposures is listed in Table 1.
