First detection of ultra-high energy emission from gamma-ray binary LS I +61 303
Utilizzando i dati dell'osservatorio LHAASO, gli autori riportano la prima rilevazione di emissione gamma a energie ultra-elevate (superiori a 100 TeV) dal sistema binario LS I +61 303, fornendo prove convincenti di un'accelerazione di particelle estrema e di una modulazione orbitale che suggerisce un meccanismo di emissione composto da processi leptonici e adronici.
