HIGH LATITUDE GAMMA RAYS ASSOCIATED WITH VIRGO
A more detailed analysis is made of the energy spectrum of the diffuse component of extragalactic gamma rays over the range of 0.3- 10 GeV, obtained fromthe EGRET instrument at the Compton Gamma Ray Observatory. The derived excess energy spectrum of high galactic latitude, b > 60°, using intercept method shows that it is correlated with Virgo cluster (over lsr) and average Virgo intensity i...

متن کاملStudies of Cosmic Rays with GeV Gamma Rays
We describe the role of GeV gamma-ray observations with GLAST-LAT (Gamma-ray Large Area Space Telescope Large Area Telescope) in identifying interaction sites of cosmic-ray proton (or hadrons) with interstellar medium (ISM). We expect to detect gamma rays from neutral pion decays in high-density ISM regions in the Galaxy, Large Magellanic Cloud, and other satellite galaxies. These gamma-ray sou...
متن کاملQuantum-gravity phenomenology with gamma rays and UHE cosmic rays
In recent years several ideas for experimental searches of effects induced by quantum properties of space-time have been discussed. Some of these ideas concern the role in quantum spacetime of the ordinary Lorentz symmetry of classical flat spacetime. Deviations from ordinary (classical) Lorentz symmetry are now believed to be rather natural in non-commutative space-times, models based on Strin...
متن کاملGalactic cosmic rays & gamma rays : a synthesis
We have developed a model which aims to reproduce observational data of many kinds related to cosmic-ray origin and propagation: direct measurements of nuclei, antiprotons, electrons and positrons, γ-rays, and synchrotron radiation. Our main results include evaluation of diffusion/convection and reacceleration models, estimates of the halo size, calculations of the interstellar positron and ant...
