The Fermi Large Area Telescope (LAT) collaboration recently released the updated results of the measurement of the cosmic ray electron (CRE) spectrum and published its first constraints on the CRE anisotropy. With respect to the previous Fermi-LAT re

We investigate the consequences of higher dimension Lorentz violating, CPT even kinetic operators that couple standard model fields to a non-zero vector field in an Effective Field Theory framework. Comparing the ultra-high energy cosmic ray spectrum

The diffuse γ-rays and neutrino emissions of the Galaxy may provide a unique tool to probe galactic cosmic rays (CR) and their interaction with the interstellar medium. At the same time, if not well understood, such emissions may be annoying backgro

The recent detection of $\gamma$-rays with energy up to 10 TeV from dense regions surrounding some Supernova Remnants (SNR) provides strong, though still not conclusive, evidence that the nucleonic component of galactic Cosmic Rays is accelerated in

A fraction of active galactic nuclei producing very high-energy (VHE) $\ensuremath{\gamma}$ rays are located in galaxy clusters. The magnetic field present in the intracluster medium would lead to conversions of VHE photons into axionlike particles (

The PAMELA collaboration recently released the ${e}^{+}$ absolute spectrum between 1 and 300 GeV in addition to the positron fraction and the ${e}^{\ensuremath{-}}$ spectrum previously measured in the same period. We use the newly developed three-dim

We set constraints on O(E/M) Lorentz Violation in QED in an effective field theory framework. A major consequence of such assumptions is the modification of the dispersion relations for electrons/positrons and photons, which in turn can affect the el

The emergence of a classical spacetime from any quantum gravity model is still a subtle and only partially understood issue. If indeed spacetime is arising as some sort of large scale condensate of more fundamental objects then it is natural to expec

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 PAMELA and Fermi LAT. We do that in terms of a novel propagation model in w
