X-ray Images of Hot Accretion Flows
We consider the X-ray emission due to bremsstrahlung processes from sphericallysymmetric low radiative-efficiency hot accretion flows around supermassive and galactic black holes. We calculate surface brightness profiles and Michelson visibility functions for a range of density profiles, ρ ∼ r−3/2+p, with 0 < p < 1, to allow for the presence of outflows. We find that although the 1 keV emitting...
متن کاملDesign and Simulation of Hot Cathode Ionization Vacuum Gauge with no X-Ray Limitations
In this paper, the MEMS type ionization gauge with no X-Ray limitations has been presented. Having the dimensions of 2.4 mm× 0.8mm × 1.4 mm, the designed gauge is 9000 times smaller than the conventional type and can operate in HV and UHV pressures up to 5×10-9 torr. Operating at the temperature of 750°C, the cathode of proposed gauge is implemented using nickel and works in a way in...
متن کاملReview x Ray crystallography
x Ray crystallography is currently the most favoured technique for structure determination of proteins and biological macromolecules. Increasingly, those interested in all branches of the biological sciences require structural information to shed light on previously unanswered questions. Furthermore, the availability of a protein structure can provide a more detailed focus for future research. ...
