# The Second CHIME/FRB Catalog of Fast Radio Bursts

CHIME/FRB Collaboration, Thomas Abbott, Bridget C. Andersen et al., 2026. _arXiv_.

4,539 bursts from 25 July 2018 to 15 September 2023, from 3,641 sources, including 981 bursts from 83 known repeaters. Each has a sky position to about 10 arcminutes, exposure and sensitivity, a 400–800 MHz dynamic spectrum at 0.983 ms resolution, and fitted width, dispersion, scattering and flux. All Catalog 1 bursts are reprocessed and earlier inferences hold.
