Pulsar Gleaners

Pulsar discoveries from public archive data.

Pulsar Gleaners is a pulsar search project based on publicly available FAST observations. Some pulsars were detected in observations originally obtained for other scientific purposes or in non-central beams. This project aims to fully exploit the scientific potential of archival FAST data through reprocessing and dedicated pulsar search techniques.

View on GitHub

The repository includes folded data diagnostic plots (fold/) and timing solutions (.par and .tim files) for some pulsars.

This work is based on archival data from the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We gratefully acknowledge all FAST project PIs who made the original observations publicly available. This project is entirely based on archival data products and demonstrates the additional scientific return enabled by archival data reuse.
