HerMES: Herschel Extragalactic Survey Catalog at 250 Microns

A 380-square-degree nested-field survey conducted by the Herschel Space Observatory's SPIRE instrument. The catalog provides positions at 250 microns, capturing redshifted thermal emission from interstellar dust to trace obscured star formation. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Identify galaxies with high rates of dust-obscured star formation based on 250-micron flux.
• Study the relationship between dust emission and galaxy evolution across nested survey fields.
• Cross-match multiwavelength datasets to form a complete picture of galaxy spectral energy distributions.
• Analyze the spatial distribution of star-forming galaxies captured by the SPIRE instrument.

Strengths

• Survey covers a total of 380 square degrees across nested fields.
• Data captures critical wavelengths (250, 350, 500 microns) for studying dust-obscured star formation.
• Produced by the National Aeronautics and Space Administration, a recognized space agency.

Limitations

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