Probing UHECR production in Centaurus A using secondary neutrinos and gamma-rays

In this paper the production of neutrinos and photons by ultra high energy cosmic rays (UHECR) interacting with the extragalactic background radiation is studied. Centaurus A is assumed as the prime source of UHECR and the possibility to identify this source by detecting the secondary neutrinos and photons produced in the propagation is investigated. Fifteen astrophysical models regarding three extragalactic magnetic fields (EGMF) and five composition abundances are simulated. The results show that the possibility of detection depends highly on the astrophysical model considered, specially the intensity of the magnetic field. The flux and arrival direction are investigated. The possibility to detected Cen A as a point source and the potentiality for an anisotropic signal are evaluated. For some combinations of EGMF and composition, Cen A could be identified by future experiments by the detection of secondary neutrinos in the energy range from $10^{14}$ to $10^{17}$ eV.
