چکیده
ABSTRACT The models currently used for the analysis of reflection spectra black holes usually assume a disc with constant ionization and electron density. However, there is some debate on impact these assumptions estimate properties sources, in particular when fits suggest very steep emissivity profiles inner part accretion disc. In this work, we re-analyse selected set high-quality NuSTAR Suzaku data Galactic fit component three different models: relxill_nk, which parameter density are constant, relxillion_nk, where still but profile described by power law, relxilldgrad_nk, law calculated self-consistently from emissivity. While relxillion_nk can better, do not find any substantial difference sources among models. Our conclusion that probably sufficient, most cases, to available X-ray accreting holes.

Direct measurements of Bragg-reflection phases in x-ray crystallography
We present a reference-beam x-ray-diffraction technique applied to a good-quality protein crystal. The technique is based on a multiple-beam diffraction principle and employs a modified oscillation camera in a Bragg inclined geometry, which allows a simultaneous measurement of both magnitudes and triplet phases of a large number of Bragg reflections from the sample. This work demonstrates that ...
متن کاملReflection of attosecond x-ray free electron laser pulses.
In order to utilize hard x-ray free electron lasers (XFEL's) when they are extended to attosecond pulse lengths, it is necessary to choose optical elements with minimal response time. Specular grazing-incidence optics made of low-Z materials are popular candidates for reflectors since they are likely to withstand x-ray damage and provide sufficiently large reflectivities. Using linear-optics re...
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...
