On an extragalactic origin of the dominant part of the hadronic cosmic rays

R. Plaga

The possibility that the major part of all extrasolar hadronic cosmic rays with energies above 10 MeV/n is of extragalactic origin is discussed. Recent observational results on the…

Cluster Radio Relics as a Tracer of Shock Waves of the Large-Scale Structure Formation

Torsten A. Ensslin, Peter L. Biermann, Ulrich Klein +1

We present evidence for the existence of shock waves caused by the formation of the large-scale structure. In some clusters of galaxies peripherally located sources of extended dif…

Survival of Substructure within Dark Matter Haloes

Giuseppe Tormen, Antonaldo Diaferio, David Syer

Using high resolution cosmological N-body simulations, we investigate the survival of dark matter satellites falling into larger haloes. Satellites preserve their identity for some…

Very High Energy Photons in Universe

F. A. Aharonian

I discuss the recent exciting results of discovery of TeV photons from several galactic and extragalactic sources, and highlight some objectives of VHE gamma ray astronomy that can…

Stereo Imaging of VHE Gamma-Ray Sources

F. A. Aharonian, A. K. Konopelko

We describe the features of the stereoscopic approach in the imaging atmospheric Cherenkov technique, and discuss the performance of future low threshold telescope arrays.

Cosmic-String-Seeded Structure Formation

P. P. Avelino, E. P. S. Shellard, J. H. P. Wu +1

We describe the results of high-resolution numerical simulations of string-induced structure formation in open universes and those with a non-zero cosmological constant. For models…
