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…
Model independent interpretation of recent CR lepton data after AMS-02
Daniele Gaggero, Luca Maccione
We model the CR leptonic fluxes above 20 GeV in terms of a superposition of a standard and a charge symmetric extra component, which we generically describe as power-laws in moment…
Galactic electron and positron properties from cosmic ray and radio observations
D. Grasso, G. Di Bernardo, C. Evoli +2
We perform a consistent modeling of cosmic ray electrons, positrons and of the radio emission of the Galaxy. For the time we reproduce all relevant data sets between 1 GeV and 1 Te…
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…
