Galactic morphology and evolution through X-ray spectroscopy of the interstellar medium
Abstract
The interstellar medium (ISM) plays a key role in the evolution of the Galaxy: it is enriched by heavy elements produced in stars and acts as reservoir for new generations of stars. The circumgalactic medium (CGM), i.e. the interface between the galaxies and the intergalactic medium (IGM), is another important reservoir of gas for star formation in the Galactic disk and the depository of Galactic feedback. It is thought to be highly ionized and to contain the bulk of the missing baryons. It is possible to study spatial extent, thermal state and metal content of ISM, CGM and IGM, and their interaction with the nearby galaxies and the Milky Way, through combined UV / X-ray spectroscopy of background sources. In this talk, I will provide a brief introduction on the ISM and the dedicated high-resolution UV / X-ray spectroscopy of compact objects like X-ray binaries and AGN. The structure, dynamics and chemistry of the ISM will be discussed as well as its interaction with the Galactic evolution....
