We present observations of the X-ray halo around the LMXB GX 13+1 from the Chandra X-ray telescope. The halo is caused by scattering in interstellar dust grains, and we use it to diagnose the line-of-sight position, size distribution, and density of the grains. Using the intrinsic energy resolution of Chandra's ACIS CCDs and the recent calibration observation of the Chandra point spread function (PSF), we were able to extract the halo fraction as a function of energy and off-axis angle. We…

THE X-RAY HALO OF CEN X-3
Using two Chandra observations, we have derived estimates of the dust distribution and distance to the eclipsing high-mass X-ray binary Cen X-3 using the energy-resolved dust-scattered X-ray halo. By
The X-ray halo of GX 5-1
Using Chandra observations we have measured the energy-resolved dust-scattered X-ray halo around the low-mass X-ray binary GX 5-1, which shows signs of both singly and multiply scattered X-rays. We

Absorption and scattering by interstellar dust: an XMM-Newton observation of Cyg X-2
We present results of the XMM-Newton observation of the bright X-ray binary Cyg X-2. In our analysis we focus on the absorption and scattering of the X-ray emission by interstellar dust distributed
Geometric Distance Determination Using Type I X-Ray Bursts
With the excellent angular resolution of the Chandra X-Ray Observatory, it is possible to geometrically determine the distance to variable Galactic sources, based on the phenomenon that scattered
A STUDY OF THE X-RAY DUST SCATTERING HALO OF CYG X-1 WITH A CROSS-CORRELATION METHOD
X-ray photons scattered by the interstellar medium carry information about dust distribution, dust grain model, scattering cross section, and the distance of the source; they also take a longer time
Chandra Observations of the X-Ray Halo around the Crab Nebula
Two Chandra observations have been used to search for thermal X-ray emission from within and around the Crab Nebula. Dead time was minimized by excluding the brightest part of the nebula from the
Determining interstellar dust properties with scattered X-ray halo
X-ray photons, emitted by X-ray sources, are absorbed and scattered by dust grains when they travel through interstellar medium. The scattered photons within small angles result in a diffuse X-ray
Monte Carlo Simulation of the X-Ray Halos of GX 5−1 and GX 13+1 to Test Models of Insterstellar Dust Grains
Simulated dust-scattered X-ray halos, generated by a three-dimensional ray-tracing Monte Carlo code, are fitted to the observed halos of GX 5−1 and GX 13+1 by automatic adjustment of parameters that
