X-rays are a central ingredient moderating the gas chemistry of cosmic bodies in the universe. In this comparison a set of publications are presented from the field of X-ray Astronomy. This field has seen an increased interest since the launch of space observatories like Chandra X-ray Observatory and XMM - Newton. This is the fifth comparison of a set that covers X-ray observations on various cosmic body types: comets, https://orkg.org/comparison/R274032/ planets, https://orkg.org/comparison/R275000/ , the sun, https://orkg.org/comparison/R282510/ the stars https://orkg.org/comparison/R282511/ and warm-hot intergalactic medium. This set of comparisons is also a direct evolution from published comparisons about the complementary topic of laboratory X-ray measurements in Highly Charged Ions (HCIs).
ORKG Comparisons have changed. We have added new features and improved the user interface. Comparisons might look slightly different, but the comparison data itself remains unchanged.
