"Active Galactic Nuclei (AGNs) power the\r\nmost luminous sources in the Universe, and generate very energetic large-scale radio\r\njets. These processes are important in galaxy formation models and numerical simulations,\r\nwhich require energy from AGNs to prevent central gas from overcooling.\r\nIn this thesis we use hydrodynamical simulations to explore the impact of jets on\r\nthe intra-galactic medium of individual halos, with particular focus on massive galaxies.\r\nThe simulations are performed with the FLASH code, and we took advantage of\r\nthe Adaptive Mesh Refinement scheme to deal with the complex, multiscale physics\r\nof AGNs on scales ranging from Megaparsec down to a few tens of parsecs.\r\nIn the first part of this thesis we describe in detail the first few millions years of\r\nAGN jets, identifying precise evolutionary stages and testing our findings against theoretical\r\nmodels. We discuss gas circulation within the “cocoon” carved by the jet as a\r\npossible self-regulation mechanism for jet activities.\r\nIn the second part, we extend the analysis to cosmologically relevant timescales,\r\nand carry on a detailed thermodynamyc analysis of the jet-gas system, including mechanical\r\nwork, global energy transfer and volume fraction of the heated gas. Finally,\r\nwe present a few extensions of our model such as multiple jet events, and take a few\r\nsteps towards direct comparison with X-ray observations."^^ . "2015" . . . . . . . "Salvatore"^^ .
