XMM-CDFS: 5-10 keV X-ray Source Catalog from Deep Survey

A catalog of 137 X-ray sources detected in the 5-10 keV energy band from the XMM-Newton Deep Survey in the Chandra Deep Field South. The survey, conducted by NASA, has a nominal exposure time of 3.45 Ms and flux limits of 9.5 x 10^-16 erg/s/cm^2. Redshifts are available for approximately 92% of the sources, and the catalog includes cross-identifications with Chandra data.

Use Cases

• Studying the spectral properties of obscured and Compton-thick AGN based on the survey's focus.
• Analyzing X-ray source number counts in the 5-10 keV band for comparison with other works.
• Investigating the spatial distribution of XMM-Newton background components (cosmic, particle, soft protons) based on the detailed decomposition.
• Cross-correlating X-ray source catalogs with multi-wavelength data from the CDFS area.

Strengths

• Deep survey with a 3.45-Ms nominal exposure time, described as the deepest XMM-Newton survey in the 5-10 keV band.
• High redshift completeness, with spectroscopic or photometric redshifts available for ~92% of the 137 sources.
• Detailed background modeling using extensive simulations to reproduce spatial properties.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown for the full dataset, which may limit suitability assessment.
