权威快报丨“拉索”首次揭示黑洞在宇宙线起源中的作用

Core Viewpoint - The LHAASO (Large High Altitude Air Shower Observatory) in Daocheng, Sichuan Province, has systematically detected five ultra-high-energy gamma-ray signals from microquasars formed by the interaction of black holes and companion stars, providing crucial evidence for understanding the origin of cosmic rays [1] Group 1 - The detection of gamma-ray signals indicates that microquasars act as powerful "particle accelerators," capable of accelerating cosmic rays to energies at and above the "knee" region of the cosmic ray energy spectrum [1] - The "knee" refers to a specific structure in the cosmic ray energy spectrum, occurring around 30 trillion electron volts, where the number of cosmic rays sharply decreases [1] - This discovery offers key observational evidence to address the long-standing mystery of the formation of the cosmic ray "knee" and points to new directions for solving this scientific challenge [1]
