Περίληψη :
High resolution X-ray spectroscopy has first become available in the late 90s, with the advent of the two X-ray grating spectrometers onboard the two NASA and ESA satellites Chandra and XMM-Newton, and is now receiving a new strong momentum with the launch of the JAXA-NASA satellite XRISM and that of several other medium-size or large X-ray spectroscopic mission that will be launched over the next two decades. Among the many fields of research that X-ray spectroscopy opened, two of the most important are those of the Universe and galaxy’s missing baryons and of AGN outflows and their energy impact on their host galaxy and surrounding CGM (feedback). The thorough investigation of both fields also need adequate modelling, and AGN outflows can only be fully assessed through time-resolved X-ray spectroscopy.
In this seminar I will present a quick overview of my research in these two fields over the past two decades and show the most recent results that my collaborators and I have reached in these fields.
