Models for galactic cosmic-ray propagation [PDF]
Advances in Space Research, 2001 A new numerical model of particle propagation in the Galaxy has been developed, which allows the study of cosmic-ray and gamma-ray production and propagation in 2D or 3D, including a full reaction network. This is a further development of the code which has been used for studies of cosmic ray reacceleration, Galactic halo size, antiprotons and ...

The origin of cosmic rays and TeV gamma-ray astronomy
EPJ Web of Conferences, 2013 Cosmic rays are accelerated to high energies in Galactic and extragalactic objects like Supernova remnants (SNR) and active galactic nuclei (AGN). How these accelerators work and how efficient they accelerate different types of particles to energies of ...

The HiSCORE concept for gamma-ray and cosmic-ray astrophysics beyond 10\,TeV [PDF]
, 2014 Air-shower measurements in the primary energy range beyond 10 TeV can be used to address important questions of astroparticle and particle physics. The most prominent among these questions are the search for the origin of charged Galactic cosmic rays and

Galactic cosmic rays after the AMS-02 observations
Physical Review D, 2019 The unprecedented quality of the data collected by the AMS-02 experiment onboard the International Space Station allowed us to address subtle questions concerning the origin and propagation of cosmic rays.

Deciphering the Dipole Anisotropy of Galactic Cosmic Rays. [PDF]
Physical Review Letters, 2016 Recent measurements of the dipole anisotropy in the arrival directions of Galactic cosmic rays (CRs) indicate a strong energy dependence of the dipole amplitude and phase in the TeV-PeV range.

COSMIC RAY PROPAGATION IN GALACTIC TURBULENCE [PDF]
The Astrophysical Journal, 2014 We revisit propagation of galactic cosmic rays (CRs) in light of recent advances in CR diffusion theory in realistic interstellar turbulence. We use a tested model of turbulence in which it has been shown that fast modes dominate scattering of CRs. As a result, propagation becomes inhomogeneous and environment dependent.

Origin of small-scale anisotropies in Galactic cosmic rays [PDF]
, 2016 The arrival directions of Galactic cosmic rays are highly isotropic. This is expected from the presence of turbulent magnetic fields in our Galactic environment that repeatedly scatter charged cosmic rays during propagation.

Transition from Galactic to extragalactic cosmic rays and cosmic ray anisotropy
EPJ Web of Conferences, 2013 This talk based on results of ref. [1], where we constrain the energy at which the transition from Galactic to extragalactic cosmic rays occurs by computing the anisotropy at Earth of cosmic rays emitted by Galactic sources.

Giant Molecular Clouds as probes of of Galactic Cosmic Rays with Fermi-LAT [PDF]
EPJ Web of Conferences, 2019 Direct measurements of Cosmic Rays (CRs) can not extend much further than the Solar System. In order to probe the so-called “sea” of Galactic Cosmic Rays, one should rely on secondary emission.
