CfA Redshift Catalog: 58,738 Galaxies with Velocity Data

58,738 astronomical objects comprise the CfA Redshift Catalog, incorporating velocity data from sources like the Whipple Observatory and earlier compilations. The NASA HEASARC assembled this version in February 2001 based on the June 1995 release from CDS/ADC. It was primarily created for studying the large-scale structure of the universe.

Use Cases

• Mapping the large-scale structure of the universe based on galaxy redshift information.
• Studying galaxy kinematics and distributions using compiled radial velocity data.
• Cross-referencing celestial objects using included identifiers like UGC numbers.
• Analyzing galaxy brightness using the included BT magnitudes.

Strengths

• Contains 57,536 objects in the main catalog and 1,202 high-redshift galaxies.
• Incorporates data from multiple authoritative sources, including the Whipple Observatory.
• Includes increased accuracy in velocity source information.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The catalog is described as not necessarily complete in categories like diameter, magnitude, and cross-references.
