Anti-GZK effect in Ultra High Energy Cosmic Rays diffusive propagation
R. Aloisio, V. S. Berezinsky
We discuss the antiGZK effect in the diffusive propagation of ultra high energy protons in intergalactic magnetic fields, which consists in a jump-like increase of the maximum dist…
Ultra High Energy Cosmic Rays Spectra in Top-Down models
R. Aloisio, V. Berezinsky, M. Kachelriess
In this work we present a detailed computation of the spectra of UHECR in the top-down scenario. We compare the spectra of hadrons obtained by two different methods in QCD and supe…
Multiwavelength Observation of WIMP Annihilation
Roberto Aloisio
The annihilation of neutralino dark matter may result in observable signals in different wavelength. In the present paper we will discuss the effect of neutralino annihilation in t…
Diffusive propagation of UHECR and the propagation theorem
R. Aloisio, V. Berezinsky
We present a detailed analytical study of the propagation of ultra high energy (UHE) particles in extragalactic magnetic fields. The crucial parameter which affects the diffuse spe…
Neutralino Annihilation at the Galactic Center Revisited
Roberto Aloisio, Pasquale Blasi, Angela V. Olinto
The annihilation of neutralino dark matter in the Galactic Center (GC) may result in radio signals that can be used to detect or constrain the dark matter halo density profile or d…
