X-ray reflection in a sample of X-ray bright ultraluminous X-ray sources [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2010
We apply a reflection-based model to the best available XMM-Newton spectra of X-ray bright UltraLuminous X-ray (ULX) sources (NGC 1313 X-1, NGC 1313 X-2, M 81 X-6, Holmberg IX X-1, NGC 5408 X-1 and Holmberg II X-1). A spectral drop is apparent in the data of all the sources at energies 6-7 keV.

Oxygen K-edge X-ray Absorption Spectra

open access: yesChemical Reviews, 2020
We review oxygen K-edge X-ray absorption spectra of both molecules and solids. We start with an overview of the main experimental aspects of oxygen K-edge X-ray absorption measurements including X-ray sources, monochromators, and detection schemes.
