Microquasar V4641 Sgr and Its Deep Investigation with LACT as a Super-PeVatron of Cosmic Rays [PDF]

open access: yesResearch
Several instruments, including LHAASO, have measured γ-ray emission from the direction of V4641 Sgr, a well known microquasar. The emission measured with LHAASO is best described as a power-law spectrum extending into the ultra-high-energy regime with no

Insight-HXMT observations of jet-like corona in a black hole X-ray binary MAXI J1820+070

open access: yesNature Communications, 2021
Evolution of accretion disk and corona during outbursts in black hole binary systems is still unclear. Here, the authors show spectral analysis of MAXI J1820+070 and propose a scenario of a dynamical corona to explain the evolution of the reflection ...
