用好“拉索”，揭示宇宙线起源之谜（奋进“十五五”·一线见闻）

Core Insights - The "LHAASO" observatory has made significant discoveries regarding cosmic rays, particularly in the "knee" region of the energy spectrum, revealing new sources of high-energy cosmic rays [1][2] - The findings indicate that black hole accretion-driven microquasars are likely candidates for the origin of these high-energy cosmic rays, providing new insights into extreme astrophysical processes [1][2] Group 1: Research and Discoveries - The "LHAASO" observatory, located at an altitude of 4410 meters in Sichuan, is the world's most sensitive ultra-high-energy gamma-ray detection facility, designed to decode high-energy particle signals from deep space [2][3] - Initial research faced challenges due to the lack of a unified coordinate system among the three detector arrays, which required extensive simulation and adjustments [2] - The unexpected "bump" in the knee region of the cosmic ray proton energy spectrum suggests the existence of new sources capable of producing extremely high-energy cosmic rays [2] Group 2: Future Plans and Goals - The team plans to measure a broader range of proton energy spectra, aiming to cover four orders of magnitude in energy range [2] - Future research will focus on deepening scientific data analysis and promoting technological upgrades to address major international research questions in the field of cosmic ray studies [2]
