X-ray Spectroscopy of Candidate Ultracompact X-ray Binaries

, 2005
We present high-resolution spectroscopy of the neutron star/low-mass X-ray binaries (LMXBs) 4U 1850-087 and 4U 0513-40 as part of our continuing study of known and candidate ultracompact binaries.

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.

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.

Adsorption of oleic acid on magnetite facets

Communications Chemistry, 2022
Metal oxide nanoparticles functionalized by organic molecules are important building blocks for nanocomposites. Here, the authors study the adsorption of oleic acid on magnetite (001) and (111) surfaces experimentally by SXRD, LEED, FT-IRRAS and XRR, and

BAT X-ray Survey - III: X-ray Spectra and Statistical Properties [PDF]

, 2007
In this concluding part of the series of three papers dedicated to the Swift/BAT hard X-ray survey (BXS), we focus on the X-ray spectral analysis and statistical properties of the source sample.

Linking Jet Emission, X-ray States and Hard X-ray Tails in the Neutron Star X-ray Binary GX 17+2

, 2007
We present the results from simultaneous radio (Very Large Array) and X-ray (Rossi-X-ray Timing Explorer) observations of the Z-type neutron star X-ray binary GX~17+2.

Bimodality of Wind-fed Accretion in High Mass X-ray Binaries [PDF]

, 2014
We study an influence of X-ray photo-ionization from an accreting neutron star in a high mass X-ray binary. Our aim is to unveil a new principle governing X-ray luminosities of X-ray binaries, with a simple analysis of fluid equations simulating line-driven wind flow under influence of X-ray irradiation.

Modeling the X-ray Contribution of X-ray Binary Jets

, 2003
Astrophysical jets exist in both XRBs and AGN, and seem to share common features, particularly in the radio. While AGN jets are known to emit X-rays, the situation for XRB jets is not so clear.

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 ...

Diffuse X-ray scattering from polished silicon: application of the distorted wave Born approximation

Journal of Synchrotron Radiation, 2022
Measured diffuse X-ray scattering data for a `smooth' as well as for a `rough' silicon sample were fit to theoretical expressions within the distorted wave Born approximation (DWBA).
