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