ASTROFLOW: A Real-Time End-to-End Pipeline for Radio Single-Pulse Searches
Guanhong Lin, Dejia Zhou, Jianli Zhang +20
Fast radio bursts (FRBs) are extremely bright, millisecond duration cosmic transients of unknown origin. The growing number of wide-field and high-time-resolution radio surveys, pa…
