TeVCat: Catalog of Very-High-Energy Gamma-Ray Sources

TeVCat is an online catalog for very-high-energy (VHE) gamma-ray astronomy, listing sources with energies above approximately 50 GeV. The catalog and website are maintained by Scott Wakely and Deirdre Horan at the University of Chicago. This table, provided by NASA HEASARC, was first ingested in July 2017 and is updated automatically within days of changes to the main catalog.

Use Cases

• Mapping celestial gamma-ray sources based on the catalog's sky maps.
• Analyzing source characteristics and visibility based on the scientific information and plotters.
• Staying informed on new discoveries via the linked references and automatic updates.
• Cross-referencing VHE sources with other astronomical datasets for multi-wavelength studies.

Strengths

• Automatically updated within days of changes to the primary source at the University of Chicago.
• Provides interactive resources like sky maps, visibility plotters, and linked scientific references.
• Maintained by named experts (Scott Wakely and Deirdre Horan) at a reputable institution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific data volume are unknown, which may limit suitability assessment.
