NGC 4472: Chandra X-Ray Point Source Catalog for a Virgo Cluster Galaxy

147 X-ray point sources detected in the giant elliptical galaxy NGC 4472 using the Chandra ACIS-S instrument. The catalog correlates 30 of these sources with optical globular cluster candidates, identifying likely low-mass X-ray binaries. This table was created by NASA's HEASARC in May 2007 based on data from a published astrophysical study.

Use Cases

• Identifying low-mass X-ray binaries based on X-ray source correlation with globular clusters.
• Analyzing the fraction of X-ray sources in globular clusters versus the field star population.
• Studying the properties of point sources in a nearby giant elliptical galaxy within the Virgo Cluster.

Strengths

• Contains 147 detected X-ray point sources with a low false-source probability detection threshold of 10^-6.
• Correlates 30 X-ray sources with optical globular cluster candidates, providing multi-wavelength context.
• Data originates from a peer-reviewed study using Chandra and Hubble Space Telescope observations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The full list of 1102 optical globular cluster candidates is not included in this table.
