Diffuse emission measurement with INTEGRAL/SPI as indirect probe of cosmic-ray electrons and positrons
Galaxy: general ?Galaxy structure ?gamma rays observations
2011/8/24
Significant advances have been made in the understanding of the diffuse Galactic hard X-ray continuum emission using data from the INTEGRAL observatory. The diffuse hard power-law component seen with ...
A possible approach to three-dimensional cosmic-ray propagation in the Galaxy IV. Electrons and electron-induced gamma-rays
three-dimensional cosmic-ray propagation the Galaxy IV. Electrons
2011/1/11
Based on the diffusion-halo model for cosmic-ray (CR) propagation, including stochastic reacceleration due to collisions with hydromagnetic turbulence, we study the behavior of the electron component ...
A new limit on the Ultra-High-Energy Cosmic-Ray flux with the Westerbork Synthesis Radio Telescope

Research in many areas of modern physics such as, e.g., indirect searches for dark matter and particle acceleration in SNR shocks, rely heavily on studies of cosmic rays (CRs) and associated diffuse e...
Time-variability in the Interstellar Boundary Conditions of the Heliosphere over the past 60,000 years: Impact of the Solar Journey on the Galactic Cosmic Ray Flux at Earth
Time-variability the Interstellar Boundary Conditions
2011/1/10
During the solar journey through galactic space, variations in the physical properties of the surrounding interstellar material (ISM) modify the heliosphere and modulate the flux of galactic cosmic ra...
High Energy Cosmic-ray Diffusion in Molecular Clouds: A Numerical Approach
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/22
The propagation of high-energy cosmic rays through giant molecular clouds constitutes a fundamental process in astronomy and astrophysics. The diffusion of cosmic-rays through these magnetically turbu...
