Stochastic Acceleration in the Galactic Center HESS Source
Stochastic acceleration of charged particles interacting resonantly with a turbulent magnetic field in a small accretion torus appears to be the likely mechanism responsible for much of Sagittarius A*’s mm and shorter wavelength spectrum. The longer wavelength radiation is produced at larger radii by electrons either diffusing from smaller scales or accelerated in situ. An important prediction ...
متن کاملA Possible Link between the Galactic Center Hess Source
Recently, HESS and other air Čerenkov telescopes have detected a source of TeV γ-rays coincident with the Galactic center. It is not yet clear whether the γ-rays are produced via leptonic or hadronic processes, so it is important to consider possible acceleration sites for the charged particles which produce the γ-rays. One exciting possibility for the origin of these particles is the central b...
متن کاملChandra Observation of the Unidentified TeV Gamma-Ray Source HESS J1303−631 in the Galactic Plane
The imaging atmospheric Cherenkov array H.E.S.S. recently discovered an extended source in the 0.4−10 TeV energy range, HESS J1303−631. We obtained a 5 ks observation with the ACIS-I array on the Chandra X-ray observatory that does not reveal an obvious compact or diffuse X-ray counterpart. Archival ROSAT images are also blank in this region. Although there are several radio pulsars within the ...
متن کاملGalaxy I . A source towards the Galactic Centre
Recent analyses of the anisotropy of cosmic rays at 10 eV (the AGASA and SUGAR data) show significant excesses from regions close to the Galactic Centre and Cygnus. Our aim is to check whether such anisotropies can be caused by single sources of charged particles. We investigate propagation of protons in two models of the Galactic regular magnetic field (with the irregular component included) a...
