Abstract (from CDS):

In this work, we present the results of the survey carried out on one of the deepest X-ray fields observed by the XMM-Newton satellite. The 1.75 Ms Ultra Narrow Deep Field (XMM175UNDF) survey is made by 13 observations taken over 2 yr with a total exposure time of 1.75 Ms (1.372 Ms after flare-filtered) in a field of 30' x 30' centered around the blazar 1ES 1553+113. We stacked the 13 observations reaching flux limits of 4.03 x 10–16, 1.3 x 10–15, and 9.8 x 10–16 erg s–1 cm–2 in the soft (0.2-2 keV), hard (2-12 keV), and full (0.2-12 keV) bands, respectively. Using a conservative threshold of Maximum Likelihood significance of ML >= 6, corresponding to 3σ, we detected 301 point-sources for which we derived positions, fluxes in different bands, and hardness ratios. Thanks to an optical follow-up that was carried out using the 10.4m the Gran Telescopio Canarias on the same field in the u'g'r'i'z' bands, combined with WISE/2MASS IR data, we identified 244 optical/IR counterpart candidates for our X-ray sources and estimated their X-ray luminosities, redshift distribution, X-ray/optical-X-ray/IR flux ratios, and absolute magnitudes. Finally, we divided this subsample into 40 non-active sources and 204 active galactic nuclei, of which 139 are classified as Seyfert galaxies and 41 as Quasars.
