Gamma rays as leptonic portals to energetic neutrinos: a new Monte Carlo approach

Gaetano Di Marco, Rafael Alves Batista, Miguel A. Sánchez-Conde

High center-of-mass electromagnetic~(EM) interactions could produce decaying heavy leptons and hadrons, leading to neutrino generation. These processes might occur in the most extr…

Ultra-high-energy Cosmic Ray Sources can be Gamma-ray Dim

Angelina Sherman, Ke Fang, Rafael Alves Batista +1

Ultra-high-energy cosmic rays, accelerated hadrons that can exceed energies of eV, are the highest-energy particles ever observed. While the sources producing UHECRs are…

Revisiting the propagation of highly-energetic gamma rays in the Galaxy

Gaetano Di Marco, Rafael Alves Batista, Miguel Ángel Sánchez-Conde

Recent gamma-ray observations have detected photons up to energies of a few PeV. These highly energetic gamma rays are emitted by the most powerful sources in the Galaxy. Propagati…
