Gamma-Ray Observations of X-ray Binaries
… collimated relativistic jets, and are called microquasars. VERITAS has conducted observations of the high-mass X-ray binary (HMXB) 1A 0535+262 and of the microquasar Cygnus X-3. Many theoretical models predict VHE emission when these sources manifest persistent relativistic jets or transient …

Search for microquasar features in cosmic ray spectra with AMS-01
… jets of cool plasma; these objects are called "microquasars". It is possible that these jets are responsible for a large flux of galactic cosmic ray protons and nuclei. The energy spectrum from these sources will be very different from the featureless power-law expected from ordinary cosmic-ray …

Black Hole Accretion Systems
… plausibly powers the jet in some GRBs, some microquasars, and all AGN. I found that GRMHD numerical models of thick disks around a rotating black hole show that an evacuated, nearly force-free magnetosphere develops as predicted by BZ (McKinney and Gammie, 2004). The BZ solution for the …

Very High Energy Gamma-Rays from Binary Systems
… and VHE gamma-ray observations of three galactic microquasars using the Rossi X-ray Timing Explorer and H.E.S.S. are presented. Although no gamma-ray detections are reported, the observations permit the derivation of upper limits to the VHE gamma-ray flux which correspond to episodes of known …

Magnetic jets from accretion disks : field structure and X-ray emission
Astrophysikalische Jets sind stark kollimierte Materieströmungen hoher Geschwindigkeit. Sie stehen im Zusammenhang mit einer Fülle verschiedener astrophysikalischer Objekte wie jungen Sternen, stellaren schwarzen Löchern ('Mikro-Quasare'), Galaxien mit aktivem Kern (AGN) und wahrscheinlich auch mit …
