Radio-Selected Gamma-Ray Burst Afterglow Catalog: 304 GRBs from 1997-2011

304 gamma-ray burst afterglows observed over 14 years, containing 2,995 flux density measurements. The catalog, compiled from VLA, EVLA, and ATCA radio telescopes, was used to analyze detection rates and peak radio luminosities. Authors from NASA used the data to produce synthetic light curves and predict behavior for new telescope arrays.

Use Cases

• Statistical analysis of radio afterglow detection rates based on pre- and post-Swift satellite epochs
• Modeling canonical radio light curve peaks based on 8.5 GHz band measurements
• Comparing peak radio luminosities across GRB classes like short-hard bursts and X-ray flashes
• Investigating relationships between radio afterglow detectability and GRB fluence or X-ray/optical brightness
• Generating synthetic light curves for comparison with observed radio sample data

Strengths

• Contains 2,995 flux density measurements, including upper limits, across a wide frequency range (0.6 to 660 GHz)
• Covers a significant 14-year time period (1997-2011) with observations from major radio telescopes
• Provides a sample of 304 GRBs, with 95 radio-detected afterglows and 63 with multi-point light curves

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect temporal bias inherent to the specific observation programs and epochs
