Decaying neutron propagation in the galaxy and the Cosmic Ray anisotropy at 1 EeV

  journal={Journal of Physics G},
We study the cosmic ray arrival distribution expected from a source of neutrons in the galactic centre at energies around 1 EeV and compare it with the anisotropy detected by AGASA and SUGAR. Besides the point-like signal in the source direction produced by the direct neutrons, an extended signal due to the protons produced in neutron decays is expected. This associated proton signal also leads to an excess in the direction of the spiral arm. For realistic models of the regular and random… Expand

The AGASA and SUGAR Anisotropies and TeV Gamma Rays from the Galactic Center: A Possible Signature of Extremely High Energy Neutrons
Recent analysis of data sets from two extensive air shower cosmic-ray detectors shows tantalizing evidence of an anisotropic overabundance of cosmic rays toward the Galactic center region that "turnsExpand
Detectable neutrino fluxes due to enhanced cosmic ray densities in the Galactic Centre region
We examine in detail the detectability of a signal of diffuse high energy neutrinos produced in the Milky Way by the interaction of cosmic rays (CRs) with the interstellar medium (ISM). We show thatExpand
Neutrons (and Neutrinos) from the Galactic Center
The AGASA and SUGAR extensive air shower cosmic ray detectors both find tantalizing evidence of an anisotropic overabundance of cosmic rays towards the Galactic Center (GC) region that ''turns on''Expand
Sgr A East as a possible high energy neutron factory in the Galactic Centre
Abstract Sgr A East is a supernova remnant located within few parsecs from the Galactic Centre (GC). There are good reasons to believe that this object is the source of the γ-ray excess detected byExpand

Anisotropy studies around the galactic centre at EeV energies with the Auger Observatory
Data from the Pierre Auger Observatory are analyzed to search for anisotropies near the direction of the Galactic Centre at EeV energies. The exposure of the surface array in this part of the sky isExpand

The search for the origin of cosmic rays with energies above 1018 eV has made considerable progress during the past few years. With new data from the High Resolution Fly's Eye experiment in Utah andExpand
Heavy Cosmic Ray Nuclei from Extragalactic Sources above 'The Ankle'
A recent observation by the Auger Observatory group presents evidence for cosmic rays above 5.6� 10 19 eV -(56 EeV) being 'predominantly protons' coming from Active Galactic Nuclei. If, as would beExpand

A thorough search of the sky exposed at the Pierre Auger Cosmic Ray Observatory reveals no statistically significant excess of events in any small solid angle that would be indicative of a flux ofExpand
Propagation of Ultra-High Energy Cosmic Rays in Extragalactic Magnetic Fields
In this paper we will discuss the problem of Ultra High Energy Cosmic Rays (UHECR) and show that the idea of a Single Source Model established by Erlykin and Wolfendale (1997) to explain the featuresExpand


Images of very high energy cosmic ray sources in the Galaxy: I. A source towards the galactic centre
Recent analyses of the anisotropy of cosmic rays at 1018 eV (the AGASA and SUGAR data) show significant excesses from regions close to the galactic centre and Cygnus. Our aim is to check whether suchExpand
