Arches and Quintuplet Clusters: 244 X-Ray Point Sources from Chandra

The Galactic centre provides a unique laboratory for examining massive star formation. This catalog contains 244 point-like X-ray sources detected in a 100-ks Chandra ACIS observation of the Arches and Quintuplet star clusters, carried out on 2004 June 9. The table was created by NASA HEASARC in July 2007 based on CDS catalog J/MNRAS/371/38.

Use Cases

• Analyze the distribution of X-ray point sources based on the deep Chandra observation mentioned in the description
• Study the interplay between massive star formation and the nuclear environment based on the Galactic centre focus
• Cross-reference X-ray source positions with other astronomical catalogs based on the point-source catalog nature

Strengths

• Contains 244 point-like X-ray sources, providing a specific count of detected objects
• Based on a deep 100-ks observation from the Chandra ACIS instrument, indicating a substantial observational effort
• Observation date (2004 June 9) and aim point strategy are explicitly documented

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is known (244), but the number of features per row is unknown, which may limit suitability assessment
