    FAST identifies another three pulsars

    http://news.xinhuanet.com/english/20..._136819885.htm

    "The China-based FAST, the world's largest single-dish radio telescope, has discovered three new pulsars, the National Astronomical Observatories of China (NAOC) said Tuesday.

    So far, FAST has identified a total of nine pulsars since its trial operations began in September 2016.

    According to Zhang Shuxin, deputy chief of the NAOC's Guizhou branch, the discovery of more pulsars will be common for FAST in the future"

    They are planning to build 2 to 10, 30 meter radio telescopes around FAST, for resolution of the array will be around 100 times greater than currently.

    Chinese scientists are considering setting up smaller radio telescopes surrounding FAST to increase array resolution, authorities said.

    According to the FAST observation station with the National Astronomical Observatories, two to 10 radio telescopes measuring 30 meters in diameter may be set up around FAST, the world's largest single-dish radio telescope.

    The resolution of the array will be around 100 times greater than currently.

    FAST will have a more advanced radio receiver as early as end of April.

    FAST has identified 11 confirmed pulsars.

    http://www.xinhuanet.com/english/201..._137036270.htm

    China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST), the world's largest single-dish radio telescope, has discovered 11 new pulsars so far, the National Astronomical Observatories of China (NAOC) said Tuesday.

    Since FAST started trial operations in September 2016, it has discovered 51 stars which bear features similar to pulsars, and 11 of them have been confirmed as new pulsars by observatories in other countries.

    US has confirmed a radio millisecond pulsar discovered by China's Five-hundred-meter Aperture Spherical radio Telescope (FAST).

    http://english.cas.cn/newsroom/news/...8_192089.shtml

    FAST, the world's largest single-dish radio telescope launched in 2016, has discovered more than 20 new pulsars so far.

    The millisecond pulsar discovery was made by FAST on Feb. 27 and confirmed by the Fermi-LAT team in reprocessing of Fermi data on April 18, which was a step closer to detecting low-frequency gravitational waves, the Chinese Academy of Sciences said Friday.

    The newly discovered pulsar, now named PSR J0318+0253, is confirmed to be isolated through timing of gamma-ray pulsations, making it the first result from the FAST-LAT collaboration outlined in a Memorandum of Understanding signed between a FAST team and an Fermi-LAT team.

    "This discovery demonstrated the great potential of FAST in pulsar searching, highlighting the vitality of the large aperture radio telescope in the new era," said Li Kejia, a scientist at the Kavli Institute for Astronomy and Astrophysics at Peking University.

    According to researchers, radio follow-up of Fermi-LAT unassociated sources is an effective way to find new pulsars.

    In a one-hour tracking observation with the FAST ultra-wide band receiver, the pulsar's radio pulses were detected with a spin period of 5.19 milliseconds, an estimated distance of about 4,000 light-years, making it potentially one of the faintest radio millisecond pulsars (MSPs).

    FAST to be upgraded to increase FAST's survey speed by five to six times.

    http://www.xinhuanet.com/english/201..._137193128.htm

    China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST), the world's largest single-dish radio telescope, will have with a new receiver installed to boost its efficiency in surveying the sky.

    The 19-beam L-band receiver, first of its kind worldwide, is expected to be put into use in early June and it will increase FAST's survey speed by five to six times, according to Friday's Science and Technology Daily.

    The receiver was jointly developed by scientists from China and Australia. It weighs 1.2 tonnes and cost over 20 million yuan (about 3.14 million U.S. dollars).

    Jin Chengjin, chief engineer of FAST's receiver system, said the new receiver has the highest sensitivity and will greatly improve FAST's efficiency in searching for new pulsars and spectral lines.

    China has built a new lab to support FAST operations.

    https://gbtimes.com/new-lab-for-the-...a?cat=business

    The Chinese Academy of Sciences (CAS) has opened a new lab designed to complement the Five-hundred-meter Aperture Spherical Telescope (FAST) in southwest China's Guizhou Province, according to a press release by the National Astronomical Observatories of China (NAOC).

    Known as KLFAST, the lab, located in Pingtang County, will focus on promoting the research and technological development of low frequency radio astronomy based on the telescope's findings. Further, it will promote international cooperation with the Square Kilometre Array (SKA), an international effort to build a multi radio telescope project with a total collecting area of one million square metres. If built, SKA would be 50 times more sensitive than any other radio instrument.
