XMM-Newton Deep Survey: 2-10 keV X-ray Source Catalog in the CDF-S

A 3.45-Ms nominal exposure XMM-Newton survey in the Chandra Deep Field South (CDFS) detected 339 sources in the 2-10 keV band and 137 sources in the 5-10 keV band. The catalog, presented by NASA, includes flux limits and cross-correlations with Chandra data, with redshifts available for approximately 92% of the sources. This dataset represents the deepest published XMM-Newton survey in the 5-10 keV band.

Use Cases

• Studying the spectral properties of obscured and Compton-thick AGN based on the survey's stated aim.
• Analyzing X-ray source number counts in the 2-10 keV and 5-10 keV bands for comparison with other works.
• Cross-matching and validating X-ray source catalogs using the provided identifications with Chandra data.
• Investigating the spatial distribution and components of the XMM-Newton background based on the detailed decomposition described.

Strengths

• Deep exposure with 3.45 Ms nominal observation time, providing high sensitivity.
• Contains 339 and 137 sources in two energy bands with specific flux limits (e.g., 6.6e-16 erg/s/cm² in 2-10 keV).
• High redshift coverage, with spectroscopic or photometric redshifts available for ~92% of sources.
• Includes 15 new sources previously undetected by the Chandra telescope.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect observational bias inherent to the specific deep field survey area.
