Event Information:
Most galaxies comparable to or larger than the mass of the Milky Way host hot, X-ray emitting atmospheres, and many such galaxies are radio sources. Hot atmospheres and radio jets and lobes are the ingredients of radio-mechanical active galactic nucleus (AGN) feedback. While a consensus has emerged that such feedback suppresses cooling of hot cluster atmospheres, less attention has been paid to massive galaxies where similar mechanisms are at play. I will review the results of X-ray and multi-wavelength observations of galactic atmospheres, including their chemical composition, dynamics, development of thermal instabilities, AGN heating and the correlations of their properties with the central supermassive black holes.
