An X-ray Bright Nucleus in the Low Surface Brightness Galaxy UGC 6614

, 2010
We report a study of the X-ray emission from the nuclear region of the low surface brightness (LSB) galaxy UGC 6614. Very little is known about the central objects in LSB galaxies especially their X-ray properties and X-ray spectra. In this study we have

Single-crystal x-ray diffraction structures of covalent organic frameworks

Science, 2018
Covalent organic frameworks writ large Covalent organic framework (COF) materials have been difficult to characterize structurally and to exploit because they tend to form powders or amorphous materials. Ma et al.

Drought and heat stress tolerance screening in wheat using computed tomography

Plant Methods, 2020
Background Improving abiotic stress tolerance in wheat requires large scale screening of yield components such as seed weight, seed number and single seed weight, all of which is very laborious, and a detailed analysis of seed morphology is time ...

Wind inhibition by X-ray irradiation in HMXBs: the influence of clumping and the final X-ray luminosity

, 2018
In wind-powered X-ray binaries, the radiatively driven stellar wind from the primary may be inhibited by the X-ray irradiation. This creates the feedback that limits the X-ray luminosity of the compact secondary.
