CLASH 5.8 Micron Catalog: Infrared Observations of 25 Galaxy Clusters

25 massive galaxy clusters observed by the Hubble Space Telescope and Spitzer Space Telescope as part of the CLASH Multi-Cycle Treasury program. The Hubble observations were completed in 2013, and Spitzer IRAC data covers all clusters. The catalog is provided by the National Aeronautics and Space Administration.

Use Cases

• Study galaxy cluster mass and structure based on gravitational lensing models mentioned in the description.
• Analyze galaxy properties and star formation based on multiwavelength Hubble and Spitzer observations.
• Conduct cosmological research based on observations of 25 massive clusters.
• Cross-match infrared sources from Spitzer IRAC Channels 1-4 data with other astronomical catalogs.

Strengths

• Data from two major space telescopes: Hubble and Spitzer.
• Covers 25 massive galaxy clusters, a significant sample for cluster studies.
• Includes gravitational lens models, which are a key product for astrophysical analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect observational bias inherent to the specific telescope programs.
