NGC 2903 Galaxy Chandra X-Ray Point Source Catalog

A catalog of 92 X-ray point sources detected in the central region of the barred spiral galaxy NGC 2903. The data originates from a deep observation by NASA's Chandra X-ray Observatory using the ACIS-S instrument on March 7, 2010. The study analyzes diffuse emission and point sources to investigate the nuclear starburst, potential galactic winds, and the absence of an active galactic nucleus.

Use Cases

• Studying the population and properties of compact X-ray binaries in a starburst galaxy based on the catalog of 92 point sources.
• Analyzing the correlation between diffuse X-ray emission and star-forming regions as described in the observation.
• Modeling galactic wind dynamics and potential gas outflow using the inferred terminal velocity of ~1100 km/s for the hard spectral component.
• Investigating the absence of an active galactic nucleus using the upper luminosity limit of <2e38 erg/s for any nuclear point source.

Strengths

• Contains results from a deep, targeted Chandra observation of a specific galaxy (NGC 2903).
• Catalog includes 92 detected point-like sources with a defined signal-to-noise threshold.
• Analysis includes specific physical measurements, such as thermal energy components (kT_e ~ 0.2-0.5 keV and ~3.6 keV) and an upper luminosity limit.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in BIN and HTML formats, which may require specialized tools for access and analysis.
