"Soft X-ray transient" outbursts which aren't soft

, 2003
We have accumulated multiwavelength (X-ray, optical, radio) lightcurves for the eight black hole X-ray binaries which have been observed to enter a supposed `soft X-ray transient' outburst, but remained in the low/hard state throughout the outburst ...

Magnetar-like X-ray Bursts from an Anomalous X-ray Pulsar [PDF]

, 2002
Anomalous X-ray Pulsars (AXPs) are a class of rare X-ray pulsars whose energy source has been perplexing for some 20 years. Unlike other, better understood X-ray pulsars, AXPs cannot be powered by rotation or by accretion from a binary companion, hence ...

X-ray mirrors with sub-nanometre figure errors obtained by differential deposition of thin WSi2 films

Journal of Synchrotron Radiation, 2023
Differential deposition by DC magnetron sputtering was applied to correct for figure errors of X-ray mirrors to be deployed on low-emittance synchrotron beamlines. During the deposition process, the mirrors were moved in front of a beam-defining aperture

The quiescent X-ray emission of three transient X-ray pulsars [PDF]

, 2002
We report on BeppoSAX and Chandra observations of three Hard X-Ray Transients in quiescence containing fast spinning (P10 higher, testifying that the quiescent emission mechanism is different.

X-ray luminescence computed tomography using a focused X-ray beam

, 2017
Due to the low X-ray photon utilization efficiency and low measurement sensitivity of the electron multiplying charge coupled device (EMCCD) camera setup, the collimator based narrow beam X-ray luminescence computed tomography (XLCT) usually requires a ...

Microstructural evolution during sintering of copper particles studied by laboratory diffraction contrast tomography (LabDCT)

Scientific Reports, 2017
Pressureless sintering of loose or compacted granular bodies at elevated temperature occurs by a combination of particle rearrangement, rotation, local deformation and diffusion, and grain growth.

Multi-beam X-ray ptychography using coded probes for rapid non-destructive high resolution imaging of extended samples

Scientific Reports, 2022
Imaging large areas of a sample non-destructively and with high resolution is of great interest for both science and industry. For scanning coherent X-ray diffraction microscopy, i. e., ptychography, the achievable scan area at a given spatial resolution

The growth of interest for astronomical X-ray polarimetry

, 2018
Astronomical X-ray polarimetry was first explored in the end of the 60's by pioneering rocket instruments. The craze arising from the first discoveries on stellar and supernova remnant X-ray polarization led to the addition of X-ray polarimeters on-board

Evaluation of methods for 3D imaging and analysis of vascularisation in biopreparations

Current Directions in Biomedical Engineering, 2022
Motivation: Within the field of bio-implants one topic deals with the in-vitro production of 3D tissues from cell cultures. A major challenge in the cultivation of biopreparations is the imitation of the vascular system with its surrounding tissue ...
