The Hot Universe: thermodynamics, kinematics, and chemistry of the diffuse plasma permeating the cosmic web

Aurora Simionescu
SRON Netherlands Institute for Space Research

On behalf of the Hot Universe working group of the NewAthena Science Redefinition Team, I will present the exciting science opportunities for studying the intracluster, circumgalactic, and intergalactic media with a next-generation X-ray observatory. I will introduce and motivate the science objectives that have been identified as "mission driving", as well as a few selected examples of studies that are not driving the mission requirements, but are nevertheless scientifically compelling. I will show that NewAthena will lead to transformative discoveries towards addressing two fundamental questions: "How does luminous matter assemble into the cosmic web we see today?" and "How do supernovae and supermassive black holes impact galaxy formation?".
