The Coma Cluster at γ-ray energies: multifrequency constraints
The Coma cluster exhibits evidence for a high-energetic non-thermal particle population. At frequencies > 1GHz recent radio halo observations confirm a significant spectral steepening of the volume-integrated emission. We calculate the volume-averaged high-energy spectrum due to inverse Compton scattering off the CMB radiation field and non-thermal bremsstrahlung according to an exponential cut...
متن کاملMicroquasars: hard X-ray/γ-ray emission
I review some of the basic observational details of jets from X-ray binaries, or ‘microquasars’. It is shown that in both (Z and Atoll) NS and BHC systems radio emission, and therefore jet formation, is correlated with the presence of hard (30–500 keV) X-ray emission. At γ-ray (> 500 keV) energies, the relation is not so clear. Possible physical connections between the presence of a jet, with a...
متن کاملCorrelation between the TeV γ-ray and X-ray emission from an accreting X-ray binary
The signal strength of TeV gamma rays from the accreting X-ray binary Cen X-3 shows evidence for correlation with both the RXTE/ASM and the BATSE X-ray signal strengths. The time scale for the variability of the gamma rays may be similar to that of X-rays and as short as a day.
متن کاملPolymethylmethacrylate/Silver Nanocomposite Prepared by γ-Ray
Polymethylmethacrylate-silver (PMMA/Ag) nanocomposite is synthesized by irradiating the solution of silver ions in methylmethacrylate monomer by γ-ray. In this method, polymerization of the methylmethacrylate monomer and the silver ion reduction occurred simultaneously. Optical properties of the PMMA/Ag solutions are investigated using UV-Vis spectroscopy. The structural characterizations of th...
