Astrophysics with High Energy Gamma Rays [PDF]

open access: green, 2002
Recent results, the present status and the perspectives of high energy gamma-ray astronomy are described. Since the satellite observations by the Compton Gamma Ray Observatory and its precursor missions have been reviewed extensively, emphasis is on the ...

A radiation transfer model for the Milky Way: I. Radiation fields and application to high-energy astrophysics [PDF]

open access: green, 2017
We present a solution for the ultraviolet (UV) - submillimeter (submm) interstellar radiation fields (ISRFs) of the Milky Way, derived from modelling COBE, IRAS and Planck maps of the all-sky emission in the near-, mid-, far-infrared and submm.

High-energy Astrophysics and the Virtual Observatory [PDF]

open access: bronze, 2005
The Virtual Observatory (VO) will revolutionise the way we do Astronomy by allowing easy access to all astronomical data and by making the handling and analysis of datasets at various locations across the globe much simpler and faster.

High-Energy Extragalactic Neutrino Astrophysics [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 2022
The detection of an astrophysical flux of neutrinos in the TeV–PeV energy range by the IceCube Neutrino Observatory has opened new possibilities for the study of extreme cosmic accelerators. The apparent isotropy of the neutrino arrival directions favors

Ultra High Energy Cosmic Ray Source Models: Successes, Challenges and General Predictions [PDF]

open access: yesEPJ Web of Conferences, 2023
Understanding the acceleration of Ultra High Energy Cosmic Rays is one of the great challenges of contemporary astrophysics. In this short review, we summarize the general observational constraints on their composition, spectrum and isotropy which ...

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 ...

Flavor anisotropy in the high-energy astrophysical neutrino sky [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2023
High-energy astrophysical neutrinos, with TeV–PeV energies, offer unique insight into astrophysics and particle physics. Their incoming directions and flavor composition — i.e., the proportion of νe , νμ , and ντ in their flux — are, individually ...
