Title: The Five-hundred-meter Aperture Spherical Radio Telescope (FAST) Project
Author: Di Li, Zhichen Pan

The Five-hundred-meter Aperture Spherical radio Telescope (FAST) is a Chinese mega-science project funded by the National Development and Reform Commission (NDRC) of the People's Republic of China. The National Astronomical Observatories of China (NAOC) is in charge of its construction and subsequent operation. Upon its expected completion in September 2016, FAST will surpass the 300-meter Arecibo Telescope and the 100-meter Green Bank Telescope in terms of absolute sensitivity in the 70 MHz to 3 GHz bands. In this paper, we report on the project, its current status, the key science goals, and plans for early science.

Title: 21 cm intensity mapping with the Five hundred metre Aperture Spherical Telescope
Author: George F. Smoot, Ivan Debono
Version v3

This paper describes a programme to map large-scale cosmic structures on the largest possible scales by using the Five hundred metre Aperture Spherical Telescope (FAST) to make a 21 cm (red-shifted) intensity map of the sky for the range 0.5<z<2.5. The goal is to map to the angular and spectral resolution of FAST a large swath of the sky by simple drift scans with a transverse set of beams. This approach would be complementary to galaxy surveys and could be completed before the Square Kilometre Array (SKA) could begin a more detailed and precise effort. The science would be to measure the large-scale structure on the size of the baryon acoustic oscillations and larger scale, and the results would be complementary to its contemporary observations and significant. The survey would be uniquely sensitive to the potential very large-scale features from inflation at the Grand Unified Theory (GUT) scale and complementary to observations of the cosmic microwave background.

China's colossal radio telescope begins testing

The world's largest radio telescope, which has been built in China, is beginning an intensive testing phase.
Chinese scientists report that the giant dish, which measures 500m across, is complete and has received its first signals from space.
It will now take three years to calibrate the instrument so it can become fully operational.

'FAST' telescope starts operation in Guizhou

The world's largest single-aperture spherical telescope, "FAST", starts operation in a karst valley in Pingtang county, Guizhou province, on Sunday. The size of 30 football fields, the 500-meter Aperture Spherical Telescope dwarfs Puerto Rico's 300-meter Arecibo Observatory. Construction began in March 2011 at a cost of 1.2 billion yuan ($179 million).

World's largest telescope begins installation of main cable net

The Five-hundred meter Aperture Spherical Telescope, known by the acronym FAST, is a radio telescope currently under construction in a remote area of southwest China's Guizhou province. It will be the world's largest and most sensitive radio telescope when completed by 2016. And this afternoon, the first of the main cable net, composed of 9,000 cables, will be installed at the facility.

China Announces Plans For Worlds Largest Radio Telescope

Currently, the title of worlds largest radio telescope belongs to the Arecibo Observatory in Puerto Rico, but by 2016 that is slated to change. China has begun construction of a radio telescope with 3x the capabilities of the Arecibo Observatory in a remote part of the Guizhou province in southern China. Expected to take four years to build, the Five-hundred-meter Aperture Spherical radio Telescope (FAST) will be the most advanced telescope of its kind.
