The Five-hundred-meter Aperture Spherical radio Telescope (FAST), a Chinese national science facility, welcomes submission of science proposals for the upcoming observing period scheduled from August 2023 to July 2024. Users of any nationalities or affiliations are invited to submit proposals before the deadline at 16:00 UT on 15th May 2023 through the website http://fast.bao.ac.cn/proposal_submit (the system will open on 6th April 2023). Information on the techniques and current performance of the telescope are available at http://fast.bao.ac.cn.
The FAST science operation covers both regular science programs and large programs. Please note that this Call only solicits regular science proposals, which can each request observing time no more than 80 hours. It is anticipated that about 1600 hours of observing time will be allocated to regular science programs. All proposals should make it clear that why the FAST is necessary for the requested observations. Based on the statistics of the last observing period, the oversubscription rate is 4.7 on average, and reaches 7.8 for the LST range of 18 to 22 hours, which approximately corresponds to the Galactic plane time for the FAST.
The FAST started its full operation in January 2020, and is now completing its third science observing period. A list of previously accepted science proposals, including both regular science and large programs, can be found at https://fast.bao.ac.cn/cms/category/approved_projects_en/. Note that information of future approved proposals, including titles, PI names, abstracts, and scheduling priorities, will also be posted at the website. Science data obtained through a regular science program have a proprietary period of 12 months. Please see the FAST Data Policy posted at https://fast.bao.ac.cn/cms/article/86/ for more details. To avoid duplication, proposers should query the FAST archive at https://fast.bao.ac.cn/observation_log/observed_source_search before planning observations to check if any existing data meet their scientific goals.
