HerMES: Herschel 350-Micron Extragalactic Survey Catalog

380 square degrees of nested fields mapped by the Herschel Space Observatory's SPIRE instrument at 350 microns. The HerMES legacy program captures the redshifted thermal emission from interstellar dust, which traces obscured star formation. This catalog, produced by the National Aeronautics and Space Administration, was last updated in March 2026.

Use Cases

• Model galaxy spectral energy distributions based on multi-wavelength thermal emission data.
• Study the correlation between dust-obscured and unobscured star formation rates based on reprocessed radiation measurements.
• Train machine learning models to identify high-redshift galaxies based on far-infrared photometric data.
• Conduct statistical analyses of galaxy populations across a 380 square degree survey area.

Strengths

• Covers a substantial 380 square degree survey area with nested fields ranging from 0.01 to 20 sq. deg.
• Data originates from the Herschel Space Observatory, a flagship ESA mission with NASA participation.
• Focuses on a critical wavelength (350 microns) for capturing the peak of redshifted dust emission.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale statistical modeling.
• Data is provided in a BIN format, which may require specialized tools for access and analysis.
