CLASH 8 Micron Catalog: Hubble and Spitzer Observations of 25 Galaxy Clusters

The Cluster Lensing And Supernova survey with Hubble (CLASH) Multi-Cycle Treasury program completed its Hubble Space Telescope multiwavelength observations of 25 massive galaxy clusters in 2013. The catalog includes associated data and gravitational lens models from MAST, supplemented by Spitzer IRAC observations covering all clusters. The dataset is provided by the National Aeronautics and Space Administration.

Use Cases

• Modeling gravitational lensing effects based on the available lens models.
• Analyzing galaxy cluster properties using multiwavelength observations from HST and Spitzer.
• Studying galaxy evolution in dense cluster environments based on infrared data.
• Cross-referencing optical and infrared photometry for cluster member galaxies.

Strengths

• Observations from two major space telescopes: Hubble Space Telescope and Spitzer.
• Covers 25 massive galaxy clusters, providing a substantial sample.
• Includes gravitational lens models for the observed clusters.

Limitations

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