The XMM-Newton wide-field survey in the COSMOS field II: X-ray data and the logN-logS

Abstract

We present the data analysis and the X-ray source counts for the first season of XMM-Newton observations in the COSMOS field. The survey covers ~2 deg^2 within the region of sky bounded by 9^h57.5^m<R.A.<10^h03.5^m; 1^d27.5^m<DEC<2^d57.5^m with a total net integration time of 504 ks. A maximum likelihood source detection was performed in the 0.5-2 keV, 2-4.5 keV and 4.5-10 keV energy bands and 1390 point-like sources were detected in at least one band. Detailed Monte Carlo simulations were performed to fully test the source detection method and to derive the sky coverage to be used in the computation of the logN-logS relations. The 0.5--2 keV and 2--10 keV differential logN-logS were fitted with a broken power-law model which revealed a Euclidean slope (alpha~2.5) at the bright end and a flatter slope (alpha~1.5) at faint fluxes. In the 5--10 keV energy band a single power-law provides an acceptable fit to the observed source counts with a slope alpha~2.4. A comparison with the results of previous surveys shows good agreement in all the energy bands under investigation in the overlapping flux range. We also notice a remarkable agreement between our logN-logS relations and the most recent model of the XRB. The slightly different normalizations observed in the source counts of COSMOS and previous surveys can be largely explained as a combination of low counting statistics and cosmic variance introduced by the large scale structure.
