Abstract
The standard model of cosmology (ΛCDM model) makes several well-justified assumptions about the underlying physics involved in cosmology from the early Universe up till now. Based on those assumptions the standard model of cosmology makes extremely precise, and successful, predictions about the physical properties of the Universe we live on. Even though the ΛCDM model of Cosmology has proved to be remarkably successful, there are still open questions. This thesis presents the work I have done to explore the relaxation of a few of those well-justified assumptions, in order to study the impact they could have on our current understanding of different cosmological probes. In Chapter 2, I consider possible sources - within the Physics Standard Model - of circular polarization in the Cosmic Microwave Background, and resolve the conflict between previous results in the literature. Chapter 3 shows the effects of inhomogeneous reionzation in the Lyman-α forest. Also it studies a first approach at mitigating these effects in near-future Lyman-α data. Finally, I discuss white dwarf star explosions as a constraining mechanism for primordial black holes as Dark Matter candidates in Chapter 4.
