摘 要:The history of modern astronomy is littered with game-changing discoveries and unsolved mysteries. At the forefront of discoveries and mysteries are capable engineers in its purest sense. Their drive, audacity, and general cognizance of frontiers in human knowledge help shape many subfields of astronomy including radio astronomy, high energy astronomy, time-domain astronomy, astrobiology, interstellar medium, pulsar, fast radio bursts, etc. FAST, with its key innovations such as the high cadence CAL, presents abundant opportunities for discoveries and trailblazing analysis. I will introduce recent progresses facilitated by FAST data, in the context of radio astronomy in the next decade. A few examples 1)current status of the Commensal Radio Astronomy FasT Survey (CRAFTS) , the world's first commensal survey of HI imaging, pulsar, galaxies, and FRBs, 2)the discovery of a characteristic energy of FRB 3) a unified description of FRB polarization, leading to an evolutionary picture of repeating FRBs 4)the first detection of Zeeman effect with Hi-Narrow-Self-Absorption (HINSA), etc.
