Desirable options include transmission and fluorescence mode and the possibility of X-ray emission spectroscopy.
"These violent winds can collide or produce shocks in the gas and dust around the stars, depositing large amounts of energy that produce X-ray emission that Chandra can detect," the agency added.
Conlon and colleagues noted that the Hitomi telescope had much fuzzier images than Chandra, so its data on the Perseus cluster are actually comprised of a mixture of the X-ray signals from two sources: a diffuse component of hot gas enveloping the large galaxy in the center of the cluster and X-ray emission from near the supermassive black hole in this galaxy.
It appears that the X-ray emission from each is 10 to 100 times greater than the combined radio and optical emission.

The spectrum and shape of the diffuse, or spread out, X-ray emission surrounding J0617 and extending well beyond the ring also match with expectations for a wind flowing from a pulsar.
The mission was named DXL, for Diffuse X-ray emission from the Local Galaxy and the astronomers have confirmed that much of this glow comes from a region of million-degree interstellar plasma called the local hot bubble, or LHB.
The X-ray yield in 4[pi]-geometry and the system efficiency of X-ray emission could be calculated from five-channel PIN diodes that were masked with Al foils.
To compare the time behavior of energy release manifested by hard X-ray emission and derivative of soft X-ray emission with time profile of the pion-decay emission, we used, in addition to SONG data, the Solar Spectropolarimeter (SPR-N) [37] data and GOES soft X-ray measurements.
An X-ray inspection system image sequence generally consists of a source for X-ray emission and a detector to convert radiation weakened by the UUT into visible light.
They provide full coverage of x-ray photoemission spectroscopy and x-ray absorption spectrometry (along with their many-body change transfer effects), theoretical approaches (including change transfer multiplet theory) that can be used to interpret core spectroscopies of systems, x-ray magnetic circular dichroism, and resonant x-ray emission spectroscopy.
In the early 1970s his group studied the corrosion and oxidation of nickel --thin oxide film formation using the unique combination of reflection high-energy electron diffraction and X-ray emission analysis, high-temperature oxidation, and the formation and breakdown of films in aqueous environments.
