First AGILE Catalog: 47 High-Confidence Gamma-Ray Sources (2007-2008)

From July 9, 2007 to June 30, 2008, the AGILE satellite detected 47 high-confidence gamma-ray sources. The Italian Space Agency (ASI) mission catalog includes 21 pulsars, 13 blazars, and other celestial objects like supernova remnants. NASA HEASARC created this table in March 2010 based on data from the Gamma-Ray Imaging Detector (GRID).

Use Cases

• Classifying gamma-ray source types based on the catalog's associations with pulsars, blazars, and supernova remnants.
• Analyzing spatial distribution of high-confidence sources based on the instrument's 40-degree field-of-view radius.
• Studying gamma-ray emission characteristics for energies greater than 100 MeV as detected by the GRID instrument.
• Comparing source detection against other catalogs, noting this is a significance-limited (4-sigma) and not a complete flux-limited sample.

Strengths

• Contains 47 high-confidence sources with specific object type counts (e.g., 21 pulsars, 13 blazars).
• Based on a conservative analysis using a high-quality event filter optimized for gamma-ray events.
• Data covers a defined 11-month observation period from July 2007 to June 2008.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The catalog is not a complete flux-limited sample due to non-uniform first-year AGILE sky coverage.
