LHAASO "Sees" for the First Time How Black Holes Produce the Highest-Energy Particles in the Universe
How do black holes accelerate particles to the highest energies in the universe? The latest research provides the answer. On July 31, it was learned from the Institute of High Energy Physics of the Chinese Academy of Sciences that the Large High Altitude Air Shower Observatory (LHAASO, "Lasso"), a major national scientific and technological infrastructure, has for the first time clearly observed the process by which a black hole, while devouring material from its companion star, regularly produces the highest-energy particles in the universe like a metronome, and has identified the first PeV gamma-ray variable source. The related research results were published in the *National Science Review*. Cygnus X-3 is a binary system located in the constellation Cygnus, consisting of a black hole and a massive companion star. The gravitational pull there is extremely strong, and the black hole frantically accretes the stellar wind blown off by its companion. LHAASO detected...
