Many of the most energetic phenomena in the universe display distinctive features in the X-ray band. High-energy resolution, sensitivity, timing and imaging capabilities are crucial in investigating the innermost regions of accretion around black holes, physical conditions of hot gas in the intracluster medium, as well as star formation and evolution up to the aftermath of supernova explosions.

In the last two decades, thanks to the XMM-Newton and Chandra missions, X-ray spectra have enabled a tremendous advancement in our understanding of high-energy processes in astrophysical systems, while at the same time opening new questions. The recent launch of the XRISM X-ray observatory marks the start a new exciting chapter in the exploration of these themes. The restart of the industrial activities of the "reformulated" Large-class X-ray observatory of the European Space Agency -NewAthena - offer the prospective of further transformational discoveries in the decade to come.

XRISM unprecedented combination of effective area and energy resolution above 2 keV is revolutionizing our understanding of high-energy sources, and providing a new perspective on fundamental questions like: How are large structures formed in the universe? How are energy and matter transferred from the small scale of the black hole immediate surrounding (a few tens gravitational radii) to the host galaxy? How do supernova explosion and stars enrich and influence their environment from the small scale of a planetary system to the galaxy scale?

After the success story of the Chandra and XMM-Newton observatories, XRISM opens a new and unexplored science window. EAS is the perfect venue to discuss with the community the state-of-the-art and its transformation in light of new results. At the same time, this event will allow us to discuss further advancements in the field in view of future missions such as NewAthena.
