Swift BAT 60-Month Survey: Active Galactic Nuclei Catalog (2005-2010)

60 months of observation from March 2005 to March 2010 by the Swift Burst Alert Telescope (BAT) in the 15-55 keV band. The catalog contains 720 detected sources, of which 428 are associated with nearby active galactic nuclei (AGNs), and was created by NASA HEASARC in May 2012 based on published research. It includes at least 15 confirmed Compton-thick AGNs and refines the log N - log S distribution of AGNs above 10 keV.

Use Cases

• Analyzing the population and luminosity function of Compton-thick AGNs based on the sample of 15 confirmed objects.
• Investigating the spatial distribution of AGNs in the local universe (≤ 85 Mpc) regardless of absorption.
• Refining the log N - log S distribution of AGNs selected above 10 keV, established to ~10% precision.
• Assessing the AGN contribution to the cosmic X-ray background using a sample with negligible incompleteness.

Strengths

• Contains 428 AGNs detected with a signal-to-noise ratio of >= 5 sigma, providing a factor of ~2 larger statistics over similarly complete sets.
• Sample has negligible incompleteness and includes at least 15 bona fide Compton-thick AGNs.
• Derived a space density of 7.9 (+4.1, -2.9) x 10^-5 Mpc^-3 for Compton-thick AGNs with luminosity > 2 x 10^42 erg s^-1.

Limitations

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