A Study on the Effect of Galactic Atmospheres on Shock Induced Disruption of Extragalactic Jets (Clusters, Galaxies, Winds, Cooling)

This dissertation studies the interaction of collimated outflows of gas, or beams, from the nuclei of elliptical galaxies with the gas medium surrounding these galaxies. In particular, the distribution of the gas medium around galaxies at rest with respect to this gas medium is explored. In this case, the density and temperature of the gas varies spatially and their relationship will be determined by the energy balance of the gas in the gravitational potential defined by the galaxy. One finds that the gas environment or "atmosphere" around a galaxy can be described either as an outflowing "wind", in the case where heating dominates, or a "cooling" inflow, in the case where cooling dominates.
