Observations Of Extended Very-high-energy Halos Around Geminga And Monogem With The LHAASO-KM2A
National Natural Science Foundation of China, Grant 11775233
Abstract
Gamma-ray halos around pulsars are an effective probe of particle propagation in the interstellar medium. Two halos named Geminga and Monogem are observed by the KM2A, one of the sub arrays of the Large High Altitude Air Shower Observatory (LHAASO). The significance of Geminga(Monogem) is 11 σ (7 σ) at the energy range from 25 TeV to 63 TeV. In the future, more statistics will allow us to investigate the energy-dependent morphologies.
