Centaurus A as a plausible source of ultra high energy cosmic rays registered by the Pierre Auger Observatory

For ultra high energy cosmic rays events detected by the Pierre Auger Observatory which arrive from the region near Centaurus A the positions of the corresponding sources were calculated for the two chosen galactic magnetic field models. Also the influence of extragalactic magnetic field was taken into account for different energy and ultra high energy cosmic rays type to show the possibility of correlation with Centaurus A

New stage in high-energy gamma-ray studies with GAMMA-400 after Fermi-LAT

Fermi-LAT has made a significant contribution to the study of high-energy gamma-ray diffuse emission and the observations of 3000 discrete sources. However, one third of all gamma-ray sources (both galactic and extragalactic) are unidentified, the data on the diffuse gamma-ray emission should be clarified, and signatures of dark matter particles in the high-energy gamma-ray range are not observed up to now. GAMMA-400, the currently developing gamma-ray telescope, will have angular (∼0.01∘ at 100 GeV) and energy (∼1% at 100 GeV) resolutions in the energy range of 10–1000 GeV which are better than Fermi-LAT (as well as ground gamma-ray telescopes) by a factor of 5–10. It will observe some regions of the Universe (such as the Galactic Center, Fermi Bubbles, Crab, Cygnus, etc.) in a highly elliptic orbit (without shading the telescope by the Earth) continuously for a long time. It will allow us to identify many discrete sources, to clarify the structure of extended sources, to specify the data on the diffuse emission, and to resolve gamma rays from dark matter particles
