Introduction and organization The use of synchrotron based high-energy x-ray scattering in materials/engineering programs is relatively new to both the synchrotron and engineering communities in the United States. In Europe such efforts are more advanced with engineering beam lines existent or under construction at ESRF in France, at PETRA III in Germany, and at Diamond in England. The industri...

We show that high-energy neutrinos can be efficiently produced in X-ray binaries with relativistic jets and high-mass primary stars. We consider a system where the star presents a dense equatorial wind and the jet has a small content of relativistic protons. In this scenario, neutrinos and correlated gamma-rays result from pp interactions and the subsequent pion decays. As a particular example ...

OSSE has observed seven transient black hole candidates: GRO J0422+32, GX339–4, GRS 1716–249, GRS 1009–45, 4U 1543–47, GRO J1655–40, and GRS 1915+105. Two gamma-ray spectral states are evident and, based on a limited number of contemporaneous X-ray and gamma-ray observations, these states appear to be correlated with X-ray states. The former three objects show hard spectra below 100 keV (photon...
