X-rays as a tool to reveal the interstellar dust chemistry
Abstract
We present the latest results on absorption by diffuse interstellar dust (ID) as seen in the X-rays, using high-resolution data from both XMM-Newton RGS and the Chandra gratings. The X-rays have unique advantages which makes these studies fundamental to acquire a complete picture on the ID chemistry. For example sharp and deep absorption features of Mg, Si, O and Fe, which are the building blocks of silicates, fall in the X-ray band. Therefore X-ray spectroscopy is also a powerful tool to unveil the Fe inclusion in dust. High quality data have already revealed that Mg-rich silicates are favored with respect to the Fe-rich population and that Fe is most likely in metallic form (Costantini et al. 2012). We present results on both diffuse and dense ID in our Galaxy and in nearby galaxies. This large project, which considers various lines of sight, is taking also advantage of our new laboratory absorption-measurements of several dust samples. This allows us to confront the data of present and future X-ray observatories with a complete data base of dust species....
