Norbert Werner is the leader of the “Lendület Hot Universe” research group at Eötvös Loránd University in Budapest, Hungary, an associate professor (Docent) in the Department of Theoretical Physics and Astrophysics at the Masaryk University in Brno, Czech Republic, and a specially appointed associate professor in the School of Science at Hiroshima University, Japan.
Most galaxies comparable to or larger than the mass of the Milky Way host hot, X-ray emitting atmospheres affected by stellar and active galactic nucleus (AGN) feedback. I will summarise some of the recent results of X-ray and multi-wavelength observations of galactic atmospheres, including their chemical composition, dynamics, development of thermal instabilities and AGN heating. I will then compare the observed properties of the atmospheric gas in galaxies spanning a wide range of stellar mass and star-formation rate with the predictions of the IllustrisTNG simulations. Finally, I will present new correlations between the atmospheric gas temperatures and the masses of the central supermassive black holes and discuss the results in the light of recent state of the art cosmological simulations.
