High energy neutrino astrophysics [PDF]

Nuclear Physics B - Proceedings Supplements, 1998
I give a brief discussion of possible sources of high energy neutrinos of astrophysical origin over the energy range from $\sim 10^{12}$ eV to $\sim 10^{25}$ eV. In particular I shall review predictions of the diffuse neutrino intensity.

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

Nature 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 ...
