Photon Polarization Precession Spectroscopy for High-Resolution Studies of Spinwaves
, 2014 A new type of spectroscopy for high-resolution studies of spin waves that relies on resonant scattering of hard x-rays is introduced. The energy transfer in the scattering process is encoded in the precession of the polarization vector of the scattered ...

X-ray Scattering Halos from the Galactic Center: Implications for Diffuse Emission Around SgrA*
, 2003 We consider the absorption and scattering of X-rays observed from the Galactic center. One objective is to characterize the intrinsic X-ray emission from the central black hole, SgrA*, in its quiescent and flaring states.

Photocage-initiated time-resolved solution X-ray scattering investigation of protein dimerization
IUCrJ, 2018 This work demonstrates a new method for investigating time-resolved structural changes in protein conformation and oligomerization via photocage-initiated time-resolved X-ray solution scattering by observing the ATP-driven dimerization of the MsbA ...

Polarization Dependence of Anomalous X-ray Scattering in Orbital Ordered Manganites
, 1998 In order to determine types of the orbital ordering in manganites, we study theoretically the polarization dependence of the anomalous X-ray scattering which is caused by the anisotropy of the scattering factor.

The Impact of Accurate Extinction Measurements for X-ray Spectral Models
, 2015 Interstellar extinction includes both absorption and scattering of photons from interstellar gas and dust grains, and it has the effect of altering a source's spectrum and its total observed intensity.

X-ray scatter correcting methods for digital radiographic imaging
Journal of Associated Medical Sciences, 2018 X-ray scattering correction method has been the primary means of enhancing radiographic images for quite some time. X-ray scattering is major deterioration factor that decreases image contrast and increases the image granularity in a radiographic image ...

On inverse scattering in electromagnetic field in classical relativistic mechanics at high energies [PDF]
, 2006 We consider the multidimensional Newton-Einstein equation in static electromagnetic field $$\eqalign{\dot p = F(x,\dot x), F(x,\dot x)=-\nabla V(x)+{1\over c}B(x)\dot x,\cr p={\dot x \over \sqrt{1-{|\dot x|^2 \over c^2}}}, \dot p={dp\over dt}, \dot x={dx\

Cosmological X-ray Scattering from Intergalactic Dust
, 2012 High resolution X-ray imaging offers a unique opportunity to probe the nature of dust in the z ~< 2 universe. Dust grains 0.1- 1 um in size will scatter soft X-rays, producing a diffuse "halo" image around an X-ray point source, with a brightness ~ few %

Polarization properties of X-ray millisecond pulsars
, 2009 Radiation of X-ray bursts and of accretion shocks in weakly magnetized neutron stars in low-mass X-ray binaries is produced in plane-parallel atmospheres dominated by electron scattering.
