Chandra X-Ray Binary Catalog of 38 Nearby Galaxies

5.8 Ms of Chandra X-ray observations reveal 4442 point sources across 38 nearby galaxies. The catalog supports analysis of X-ray luminosity functions for high-mass and low-mass binary populations. NASA HEASARC created this table in April 2023 based on published astrophysical research.

Use Cases

• Modeling X-ray luminosity function scaling relations based on star formation rates and stellar masses
• Investigating the influence of metallicity on high-mass X-ray binary populations
• Studying the correlation between globular cluster populations and low-mass X-ray binary excess
• Analyzing the dependence of X-ray binary luminosity functions on specific star formation rate

Strengths

• Contains 4442 X-ray point sources, including low-luminosity objects excluded from primary analysis
• Based on 5.8 Ms of Chandra ACIS data combined with multiwavelength UV-to-IR observations
• Covers 38 nearby galaxies with distances from 3.4 to 29 Mpc

Limitations

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