Core Insights - The research team led by the Purple Mountain Observatory has captured the detailed evolution of the Faraday rotation measure (RM) of a repeating fast radio burst (FRB), providing key observational evidence for the hypothesis that FRBs originate from binary star systems [1][2] Group 1: Research Findings - The team monitored the repeating fast radio burst FRB 20220529 for over two years, concluding that it likely originates from a binary star system [2] - The observed Faraday rotation measure increased by 20 times and then rapidly decreased, indicating the passage of a dense magnetized plasma cloud, which aligns with the intense activity expected in a binary star system [2] Group 2: Technological Advancements - The Five-hundred-meter Aperture Spherical Telescope (FAST) is the world's largest single-dish radio telescope, contributing to various fields such as gravitational wave detection and pulsar searches since its operation began [2] - FAST is set to undergo upgrades, including the construction of several medium-sized antennas to form a giant aperture array, enhancing spatial resolution and observational sensitivity [2][3] - Upon completion of the upgrades, FAST will serve as a more powerful "cosmic super probe," aiding scientists in understanding fundamental astrophysical mysteries [3]
