Planning Surveys of the Five-hundred-meter Aperture Spherical radio Telescope and their PTA Implications
Di Li, Chief Scientist, Radio Division, National Astronomical Observatory, China (NAOC),

The FAST telescope covers 70MHz to 3GHz with a 300-meter effective aperture, which is 2-3 times that of Arecibo.

The longest tracking time FAST is 6 hours. For extended sources, such as HI gas in the local IGM, FAST is expected to be more sensitive than SKA1. Early science results, including two special issues on RAA and SCMPA and one paper on ApJ have been published. A large fraction of the 133 open proposals from its first call are being carried out. Based on results, we are planning two major surveys, one shallow all-sky and one deep targeted survey.

I will also discuss here the potential impacts of FAST on PTA studies and the formation of CPTA.
