In higher energies above GZK cut off, a considerable increase is calculated in cosmic primary photons. In addition, event frequency distribution above energy 7×1019 eV shows increasing concentration towards super galactic plane.H A KermaniS J FatemiIranian Journal of Physics Research...
SPEs, which vary in the magnitude and frequency, will obviously also contribute to total mission doses so it is important to note that total mission exposures are only estimates. Further information on the space radiation environment that astronauts will experience is discussed in Simonsen et al.5...
Around the peak of the X-ray, optical, and radio emissions (about 160 days), the H.E.S.S. performed additional observations [63]. The obtained upper limits around the peak of the emission at lower frequency were at a flux level 10 times higher than the observed X-ray flux (Figure 9...
The dense circumnuclear environments, on the other hand, could make the study of intrinsic jet properties and their connection to the 𝛾γ-ray production more complicated. Therefore, high-frequency VLBI that is less affected by the foreground material are crucial. Indeed, a recent 86 GHz GMVA...
