X-rays provide a powerful probe since they can penetrate gas and dust over a wide range of column densities (up to $10^{24}\\ \\rm{cm}^{-2}$). The interaction (scattering and absorption) with the medium imprints spectral signatures that reflect the individual atoms which constitute the gas, molecule, or solid. In this work we investigate the ability of high resolution X-ray spectroscopy to probe the properties of cosmic grains containing iron.
