HerMES: 350 Micron Extragalactic Source Catalog from Herschel

HerMES mapped 380 square degrees of sky across nested fields ranging from 0.01 to 20 square degrees. The catalog was created using the SPIRE instrument on the Herschel Space Observatory at 350 microns, a wavelength critical for detecting dust-obscured star formation. This NASA legacy program data is stored in BIN format and was last updated in March 2026.

Use Cases

• Identify galaxies with high rates of dust-obscured star formation based on 350 micron flux density.
• Study the relationship between far-infrared emission and galaxy evolution across the survey's nested fields.
• Cross-match sources with optical or radio catalogs to build a multiwavelength understanding of galaxy properties.
• Analyze the spatial distribution of star-forming galaxies within the 380 square degree survey area.

Strengths

• Covers a total survey area of 380 square degrees.
• Uses data from the Herschel Space Observatory's SPIRE instrument, a dedicated far-infrared telescope.
• Targets the 350 micron band, which captures the peak emission from redshifted thermal dust.

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 ML tasks.
• Data is provided in a BIN format, which may require specialized tools for access and parsing.
