X-ray observations of unidentified H.E.S.S. γ-ray sources
Abstract. In a survey of the inner part of the Galaxy, performed with the H.E.S.S. Instrument (High energy stereoscopic system) in 2004 and 2005, a large number of new unidentified very high energy (VHE) γ-ray sources above an energy of 100 GeV was discovered. Often the γ-ray spectra in these sources reach energies of up to ∼ 10 TeV. These are the highest energy particles ever attributed to sin...
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 کاملX-ray follow-up observations of unidentified VHE γ-ray sources
A large fraction of the recently discovered Galactic Very High Energy (VHE) source population remains unidentified to date. VHE γ-ray emission traces high energy particles in these sources, but for example in case of hadronic processes also the gas density at the emission site. Moreover, the particles have sufficiently long lifetimes to be able to escape from their acceleration sites. Therefore...
