Modeling large scale structure from photometric surveys
… groups selected from the seventh data release of the Sloan Digital Sky Survey. The galaxy sample was selected with r-band apparent magnitudes between 17 and 21; and we update the flag criteria to select a clean galaxy catalog and detail specific tests that we perform to characterize systematic …

Modeling Astrophysical and Large-Scale Structure Signatures in Axion Cosmologies
The quest to understand the fundamental nature of dark matter (DM) remains a challenge in contemporary physics. This thesis aims at elucidating astrophysical and cosmological imprints of fuzzy dark matter (FDM), a promising class of models which find ample motivation within theories of particle …

Spherically-symmetric inhomogeneities in general relativity and their effects in cosmology
… solutions are relevant in many areas of cosmology, from perturbations in the early Universe to growth of large scale structures in the later eras. In this thesis, we first focus on a comparison between the tetrad-based method and the widely used Lemaitre-Tolman-Bondi (LTB) model for …
