"This thesis comprises research on two topics of cosmological non-linear structure\r\nformation. One part investigates the formation of neutrino lumps in the Dark Energy\r\nmodel Growing Neutrino Quintessence (GNQ). Therefor N-body simulations with\r\nrelativistic particles and non-linear scalar field equations are required. The formation\r\nof lumps is caused by a coupling between the neutrinos and a scalar Quintessence\r\nfield. The neutrino lumps induce backreaction effects, possibly invalidating GNQ\r\nas a Dark Energy model. We investigate if despite the backreaction effects a realistic\r\ncosmology is possible. For a constant coupling this is hard to realize, while\r\nwe find a realistic cosmology for a varying coupling . GNQ can be tested with\r\ncosmology by detecting the gravitational potentials of the lumps. The other part\r\ninvestigates effective fluid models for ordinary structure formation of Dark Matter.\r\nThese models aim at improving perturbative methods by averaging over small scales\r\nand taking the information on the non-perturbative dynamics on small scales from\r\nsimulations. Thereby, a renormalization procedure ensures that physical quantities\r\nare independent of the arbitrary smoothing scale. We investigate consistency of the\r\nrenormalization procedure with the Galilean Invariance of the theory."^^ . "2016" . . . . . . . "Florian"^^ . "Führer"^^ . "Florian Führer"^^ . . . . . .
