VizieR Online Data Catalog: X-ray detected sources around Spiderweb Galaxy (Tozzi+, 2022)

In this paper, we focus on the field of view within a radius of 5 arcmin (corresponding to ~2.5Mpc at z=2.156) centered on the nucleus of the Spiderweb, which results in a total of 78.5 arcmin². This region includes the solid angle covered by our observation with a sensitivity that is greater than about half of the highest sensitivity reached at the aimpoint, and with an angular resolution that is higher than 3 arcsec (FWHM). This allows us to have a smooth sky coverage, thereby avoiding large corrections when evaluating the number counts.

We identify 107 X-ray sources within a radius of 5 arcmin centered on the Spiderweb Galaxy, down to flux limits of 1.3x10^-16erg/s/cm² and 3.9x10^-16erg/s/cm² in the soft and hard band, respectively. We compute the cumulative number counts which are found to be consistent with results from X-ray deep fields in the literature.
