The X-ray team of IAASARS at National Observatory of Athens organises weekly seminars dedicated to high-energy Astrophysics. The programme is shown below. Stay tuned for the zoom credentials a few days before each meeting. They will be given in a post on this website or can be found in the event page: http://ahead.astro.noa.gr/?post_type=tribe_events
