Abstract:
Nuclear obscuration plays a key role in the initial phases of AGN
growth, yet not many highly obscured AGN are currently known beyond
the local Universe, and their search is an active topic of research.
The XMM-Newton survey in the Chandra Deep Field South (XMM-CDFS) aims
at detecting and studying the spectral properties of a significant
number of obscured and Compton-thick (NH=1024cm-2 ) AGN. The large
effective area of XMM-Newton in the 2-10 and 5-10keV bands, coupled
with a 3.45Ms nominal exposure time (2.82 and 2.45Ms after lightcurve
cleaning for MOS and PN respectively), allows us to build clean
samples in both bands, and makes the XMM-CDFS the deepest XMM-Newton
survey currently published in the 5-10keV band. The large multi-
wavelength and spectroscopic coverage of the CDFS area allows for an
immediate and abundant scientific return. In this paper, we present
the data reduction of the XMM-CDFS observations, the method for source
detection in the 2-10 and 5-10keV bands, and the resulting catalogues.
A number of 339 and 137 sources are listed in the above bands with
flux limits of 6.6x10-16 and 9.5x10-16erg/s/cm2, respectively.
The flux limits at 50% of the maximum sky coverage are 1.8x10-15 and
4.0x10-15erg/s/cm2, respectively. The catalogues have been
cross-correlated with the Chandra ones: 315 and 130 identifications
have been found with a likelihood- ratio method, respectively. A
number of 15 new sources, previously undetected by Chandra, is found;
5 of them lie in the 4Ms area. Redshifts, either spectroscopic or
photometric, are available for ∼92% of the sources. The number
counts in both bands are presented and compared to other works. The
survey coverage has been calculated with the help of two extensive
sets of simulations, one set per band. The simulations have been
produced with a newly-developed simulator, written with the aim of the
most careful reproduction of the background spatial properties. For
this reason, we present a detailed decomposition of the XMM-Newton
background into its components: cosmic, particle, and residual soft
protons. The three components have different spatial distributions.
The importance of these three components depends on the band and on
the camera; the particle background is the most important one (80-90%
of the background counts), followed by the soft protons (4-20%).
Description:
X-ray sources were detected in the 3Ms XMM-Newton observations of the
Chandra Deep Field South. Source detection was done in two steps,
first using the PWXDetect software, and then using emldetect. Sources
detected by both programs are presented in the main tables, while
sources only detected by PWXDetect are presented in the supplementary
tables. The 2-10 and 5-10keV bands were analyzed separately.
