HI and Pulsar Survey Plans of the Five-hundred-meter Aperture Spherical radio Telescope (FAST)

The Five-hundred-meter Aperture Spherical radio Telescope (FAST), currently under commissioning since its inauguration on Sep. 25, 2016, is the largest single-dish radio facility in the world. Through a collaboration with Fermi, we announced the first MSP discovered by FAST and confirmed by the Fermi team, in April of 2018. I will introduce our main survey plan, namely, a Commensal Radio Astronomy FasT Survey (CRAFTS: Li et al. 2018), which aims to deliver pulsar, ISM, galaxies, and FRB data stream simultaneously in drift-scan mode, utilizing 19 coherent beams of the focal-plane-feedhorn-array. Such a survey is expected to discover ~1000 new pulsars, >300 K galaxies, and provide a state-of-art data set of the gaseous environment of the MilkyWay. I will also discuss a few targeted surveys, particularly, the pulsar search efforts in coordination with Fermi and the study of dark molecular gas (DMG) through both HI absorption and diffuse gamma-ray emission.
