【新华社】“中国天眼”找到快速射电暴起源关键证据

Core Viewpoint - The research team led by the Purple Mountain Observatory of the Chinese Academy of Sciences has captured the detailed evolution process of the Faraday rotation measure (RM) of a repeating fast radio burst (FRB), providing key observational evidence for the hypothesis that fast radio bursts originate from binary star systems [3][4]. Group 1: Research Findings - The team utilized the 500-meter Aperture Spherical Telescope (FAST) to monitor the repeating fast radio burst FRB 20220529 for over two years, concluding that it likely originates from a binary star system [3]. - The observed Faraday rotation measure exhibited a 20-fold increase followed by a rapid decrease, indicating the passage of a dense magnetized plasma cloud through the observational line, consistent with the intense activity of a companion star in a binary system [4]. Group 2: Technological Advancements - FAST, the world's largest single-dish radio telescope, has produced significant results in various fields, including gravitational wave detection, pulsar searches, and fast radio burst studies since its inception [4]. - The FAST operation and development center plans to upgrade the telescope by constructing dozens of medium-sized antennas around it, creating a giant integrated aperture array to enhance observational sensitivity and overcome the limitations of single-dish telescopes [4].
