Giant Chinese telescope "Fast" Discovers more than 900 new pulsars
Select the Chinese spherical radio telescope "FAST" With an aperture of five hundred metres, it is the largest single-dish radio telescope in the world. It has discovered more than 900 new pulsars since its inauguration in 2016.
The Chinese news agency, “Xinhua”, reported: Today, Wednesday, according to the statement of the Chinese telescope operator, today pulsars, or rapidly rotating neutron stars, arise from the explosive cores of massive, dying stars through supernova explosions.
She added that pulsars included more than 120 pulsars. Binary stars, more than 170 pulsars per millisecond, and 80 faint and intermittent pulsars. Also, over the course of more than 50 years since the discovery of the first pulsar, less than 3,000 pulsars were discovered around the world, and the number of new pulsars discovered "fast" More than three times the total number of pulsars discovered by foreign telescopes during the same period.
She noted that “the study has important implications for understanding the dense remains of dead stars in the Milky Way and their radiation characteristics.” Observing pulsars is also a major mission for FAST, which can be used to confirm the existence of gravitational radiation and black holes, and help find answers to many other key questions in physics.
Chief engineer Jiang Ping said, All employees are making every effort to improve the performance of the telescope. At present, the annual observation time of the telescope is about 5,300 hours, and it plays an important role in the continuous harvest of scientific research achievements. “FAST” is located In a deep, round karst depression in Guizhou Province, southwest China, it officially began operation in January 2020 and is believed to be the most sensitive radio telescope in the world.
