The Role of Plasma Instabilities in the Propagation of Gamma-Rays from Distant Blazars
Andrey Saveliev, Carmelo Evoli, Guenter Sigl
The observation in the GeV band of distant blazars has been recently used to put constraints on the Extragalactic Background Light (EBL) and Extragalactic Magnetic Fields (EGMF). T…
PAMELA and AMS-02 positron and electron spectra are reproduced by three-dimensional cosmic-ray modeling
Daniele Gaggero, Dario Grasso, Luca Maccione +2
The PAMELA collaboration recently released the absolute spectrum between 1 and 300 GeV in addition to the positron fraction and the spectrum previously measured in the…
Cosmic ray propagation in galactic turbulence
Carmelo Evoli, Huirong Yan
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…
Constraints on dark matter annihilations from diffuse gamma-ray emission in the Galaxy
Maryam Tavakoli, Ilias Cholis, Carmelo Evoli +1
Recent advances in gamma-ray cosmic ray, infrared and radio astronomy have allowed us to develop a significantly better understanding of the galactic medium properties in the last…
Three dimensional modeling of CR propagation
Daniele Gaggero, Luca Maccione, Giuseppe Di Bernardo +2
We present here a major upgrade of DRAGON, a numerical package that computes the propagation of a wide set of CR species from both astrophysical and exotic origin in the Galaxy in…
A unified solution to the anisotropy and gradient problems
Daniele Gaggero, Carmelo Evoli, Dario Grasso +1
The Fermi-LAT collaboration recently confirmed a discrepancy between the observed longitudinal profile of gamma-ray diffuse emission from the Galaxy and that computed with numerica…
Three-Dimensional Model of Cosmic-Ray Lepton Propagation Reproduces Data from the Alpha Magnetic Spectrometer on the International Space Station
Daniele Gaggero, Luca Maccione, Giuseppe Di Bernardo +2
We study the compatibility of Alpha Magnetic Spectrometer (AMS-02) data on the cosmic-ray (CR) positron fraction with data on the CR electron and positron spectra provided by PAMEL…
