To Understand the Radiative Processes of Pulsars and Fast Radio Bursts with the FAST

The radiative mechanism of coherent radio emission has remained an enigma since the discovery of pulsars, even with the emergence of fast radio bursts (FRBs), which exhibit similarities to the single-pulse behavior of pulsars and have opened a new window for deciphering this long-standing mystery. Besides tremendous efforts in modeling, advanced facilities are essential for solving the problem. The authors review the observational breakthroughs made with the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), which are providing pivotal insights into the underlying physics of pulsars and FRBs. This study offers a novel perspective in the era when pulsars meet FRBs, and further investigations are encouraged to utilize the high sensitivity of FAST.
