A 3D time-dependent model for Galactic cosmic rays and gamma rays
A. W. Strong, I. V. Moskalenko
In studies of cosmic-ray (CR) propagation and diffuse continuum gamma-ray emission from the Galaxy it has usually been assumed that the source function can be taken as smooth and t…
Secondary Antiprotons in Cosmic Rays
I. V. Moskalenko, A. W. Strong, J. F. Ormes +2
High energy collisions of cosmic ray (CR) nuclei with interstellar gas are believed to be the mechanism producing the majority of CR antiprotons. The distinguishing spectral shape…
Galactic propagation of positrons from particle dark-matter annihilation
I. V. Moskalenko, A. W. Strong
We have made a calculation of the propagation of positrons from dark-matter particle annihilation in the Galactic halo for different models of the dark matter halo distribution usi…
The Galactic contribution to high latitude diffuse gamma-ray emission
A. W. Strong, I. V. Moskalenko, O. Reimer
Recent evidence for a large Galactic halo, based on cosmic-ray radioactive nuclei, implies a significant contribution from inverse Compton emission at high Galactic latitudes. We p…
The GALPROP program for cosmic-ray propagation: new developments
A. W. Strong, I. V. Moskalenko
The cosmic-ray propagation code GALPROP has been generalized to include fragmentation networks of arbitrary complexity. The code can now provide an alternative to leaky-box calcula…
Galactic cosmic rays & gamma rays: a synthesis
A. W. Strong, I. V. Moskalenko
We have developed a model which aims to reproduce observational data of many kinds related to cosmic-ray origin and propagation: direct measurements of nuclei, antiprotons, electro…
