High temperature X-ray diffraction study of the U4O9 formation on UO2 sintered plates
(1991-01-01)
The surface oxidation of UO2 sintered plates at 170-275 ° C was studied in situ by high temperature X-ray diffractometry. At very low oxygen concentration, UO2 is oxidized to U4O9, while at 300°C and argon-20 vol% oxygen ...
X-ray Spectral Constraints for z~2 Massive Galaxies: The Identification of Reflection-Dominated Active Galactic Nuclei
(2011)
We use the 4Ms CDF-S survey to place direct X-ray constraints on the ubiquity of z~2 heavily obscured AGNs in K<22 BzK galaxies. Forty seven of the 222 BzK galaxies in the central region of the CDF-S are detected at X-ray ...
SU Lyn: Diagnosing the Boundary Layer with UV and Hard X-Ray Data
(IOP Publishing, 2018-08)
Symbiotic stars in which the symbiotic phenomenon is powered solely by accretion, often at an average rate that is higher than in cataclysmic variable stars, provide an important opportunity to diagnose boundary layers ...
Multielement analysis of soft drinks by X-ray fluorescence spectrometry

X-ray, UV, and optical observations of the accretion disk and boundary layer in the symbiotic star RT Crucis
(EDP Sciences, 2018-05)
Compared to mass transfer in cataclysmic variables, the nature of accretion in symbiotic binaries in which red giants transfer material to white dwarfs (WDs) has been difficult to uncover. The accretion flows in a symbiotic ...
