Planning Surveys of the Five-hundred-meter Aperture Spherical radio Telescope and their PTA Implications

报告摘要

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 of 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 are being published. A large fraction of the 133 proposals responding to FAST\'s first call are being carried out. Based on these results, we are planning two major surveys, one shallow all-sky and one deep targeted survey. These two surveys have the potential for major discoveries in pulsars, ISM, nearby galaxies, FRBs, exoplanets, etc. I will also discuss here the potential impacts of FAST on PTA studies.
