Searching for Fast Radio Transients with FAST

This paper summarizes our efforts on the fast radio transient searches by the Five-hundred-meter Aperture Spherical radio Telescope (FAST), which was realized by an efficient GPU-based single-pulse searching pipeline and the artificial intelligence detection technology. We discovered more than 100 Galactic rotating radio transients (RRATs) and 5 extragalactic fast radio bursts (FRBs) in the survey data from FAST. We have also observed known RRATs with the FAST, obtained many high signal-to-noise ratio pulses, and confirmed that RRATs are typically weak or nulling pulsars. In addition, thousands of bursts of some repeating FRBs have been detected with our newly developed pipeline, and we did statistics on the parameters of these sources. Our supersensitive observations contribute to a deeper understanding of RRATs and FRBs.
