Method to Look for Imprints of Ultrahigh Energy Nuclei Sources
G. Giacinti, D. V. Semikoz
We propose a new method to search for heavy nuclei sources, on top of background, in the Ultra-High Energy Cosmic Ray data. We apply this method to the 69 events recently published…
Ultra-high energy nuclei source in the direction to Virgo cluster
Dmitri V. Semikoz
The significant anisotropy in the arrival directions of the 69 events with energy E> 55 EeV detected by Pierre Auger collaboration is located in the 20-degree region centered near…
Ultrahigh Energy Nuclei in the Galactic Magnetic Field
G. Giacinti, M. Kachelriess, D. V. Semikoz +1
Observations are consistent with a significant fraction of heavy nuclei in the cosmic ray flux above a few times 10^19 eV. Such nuclei can be deflected considerably in the Galactic…
No evidence for gamma-ray halos around active galactic nuclei resulting from intergalactic magnetic fields
A. Neronov, D. V. Semikoz, P. G. Tinyakov +1
We analyze the gamma-ray halo around stacked AGNs reported in Ap.J.Lett., 2010, 722, L39. First, we show that the angular distribution of gamma-rays around the stacked AGNs is cons…
High Galactic latitude Fermi sources of gamma-rays with energies above 100 GeV
A. Neronov, D. V. Semikoz, Ie. Vovk
We present a catalog of sources of very high energy (E>100 GeV) gamma-rays detected by the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope at Galactic latitu…
Search for an extended VHE gamma-ray emission from Mrk 421 and Mrk 501 with the MAGIC Telescope
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +148
Context: Part of the very high energy -ray radiation coming from extragalactic sources is absorbed through the pair production process on the extragalactic background light phot…
