Cosmic rays from thermal sources
Energy spectrum of cosmic rays (CR) exhibits power-like behavior with very characteristic ”knee” structure. We consider a generalized statistical model for the production process of cosmic rays which accounts for such behavior in a natural way either by assuming existence of temperature fluctuations in the source of CR, or by assuming specific temperature distribution of CR sources. Both possib...
متن کاملSources of sub - GZK cosmic rays
We analyze the existing evidence that BL Lacertae objects (BL Lacs) are sources of the highest-energy cosmic rays. We argue that three independent signatures observed in the real data — (1) improvement of correlations with corrections of trajectories for the Galactic magnetic field; (2) connection between γ-ray and UHECR emissions; (3) non-uniform distribution of correlating rays over the sky —...
متن کاملCosmic X-ray Sources
The atmosphere of the Earth is opaque to most wavelengths of light in the infrared, in the ultraviolet and in the X-rays. Due to this fact observation of celestial objects in X-rays (in the range of energies from 0.5 to 20 keV) must be carried out outside the atmosphere at altitudes greater than 100 kilometers, namely from space. The development of X-ray astronomy had therefore to await the dev...
متن کاملDetailed analysis of observed antiprotons in cosmic rays
In the present work, the origin of antiprotons observed in cosmic rays (above the atmosphere) is analyzed in details. We have considered the origin of the primaries, (which their interactions with the interstellar medium is one of the most important sources of antiprotons) is a supernova type II then used a diffusion model for their propagation. We have used the latest parameterization for anti...
متن کاملISM : Discriminating between Cosmic Rays and X - rays
The ISM of active galaxy centers is exposed to a combination of cosmic ray, FUV and X-ray radiation. We apply PDR models to this ISM with both 'nor-mal' and highly elevated (5 × 10 −15 s −1) cosmic-ray rates and compare the results to those obtained for XDRs. Our existing PDR-XDR code is used to construct models over a 10 3 − 10 5 cm −3 density range and for 0.16-160 erg s −1 cm −2 im-pingent f...
