We study the two-dimensional surface brightness distribution of the Galactic X-ray background emission outside the central degree around Sgr A ∗ in the 6.7-keV line as measured by the Proportional Counter Array spectrometer of the Rossi X-ray Timing Explorer observatory. The use of the emission line instead of continuum (3‐20 keV) radiation and application of timevariability filtering to the long data set allows us to strongly suppress the contamination of the Galactic ridge X-ray emission…

Resolving the Galactic ridge X-ray background
We use Chandra deep observations of the Galactic Center (GC) region to improve the constraints on the unresolved fraction of the Galactic ridge X-ray background in the 4–8 keV band. We emphasize the
On the contribution of point sources to the Galactic ridge X-ray emission
We analyzed deep Chandra observations of the Galactic plane region centered at l = 28.55°, b = -0.03° with the aim to obtain the best possible constraints on the contribution of weak point sources to
Discrete sources as the origin of the Galactic X-ray ridge emission
TLDR
It is reported that at energies of ∼6–7 keV, more than 80 per cent of the seemingly diffuse X-ray emission is resolved into discrete sources, probably accreting white dwarfs and coronally active stars.
Diffuse X-Ray Sky in the Galactic Center
The Galactic Diffuse X-ray Emission (GDXE) in the Milky Way Galaxy is spatially and spectrally decomposed into the Galactic Center X-ray Emission (GCXE), the Galactic Ridge X-ray Emission (GRXE) and
The Galactic Bulge Diffuse Emission in Broadband X-Rays with NuSTAR
The diffuse hard X-ray emission that fills the Galactic center, bulge, and ridge is believed to arise from unresolved populations of X-ray binary systems. However, the identity of the dominant class
Suzaku Spectroscopy of Extended X-Ray Emission in M17
We present the results of a Suzaku spectroscopic study of soft extended X-ray emission in the H II region of M 17. The spectrum of the extended emission was obtained with a high signal-to-noise ratio
X-ray luminosities of optically selected cataclysmic variables and application to the Galactic ridge X-ray emission
By studying Swift X-ray spectra of an optically selected, non-magnetic sample of nearby cataclysmic variables (CVs), we show that there is a population with X-ray luminosity much lower than accounted
Global Distribution of Fe Kα Lines in the Galactic Center Region Observed with the Suzaku Satellite
We surveyed spatial profiles of the Fe K˛ lines in the Galactic center diffuse X-rays (GCDX), including the tran- sient region from the GCDX to the Galactic ridge X-ray emission (GRXE), with the
Is SS 433 a misaligned ultraluminous X-ray source? Constraints from its reflected signal in the Galactic plane
We evaluate the emission that must arise due to reflection of the putative collimated X-ray radiation of SS 433 by atomic gas and molecular clouds in the Galactic plane and compare the predicted
The galactic center massive black hole and nuclear star cluster
The Galactic Center is an excellent laboratory for studying phenomena and physical processes that may be occurring in many other galactic nuclei. The Center of our Milky Way is by far the closest
