Revealing hidden repeaters in the CHIME/FRB catalogue: semisupervised insights into the fast radio burst population

N. Mankatwit, P. Thongkonsing, S. Loekkesee et al., 2025. Monthly Notices of the Royal Astronomical Society 545(3), staf2178.

Semi-supervised classification (UMAP with five voting classifiers) of CHIME bursts finds dispersion measure, peak frequency and fluence the most discriminating features and flags 36 apparent one-off sources as repeater candidates.
