| Abstract | |
The detection of a peak in the radial correlation function in galaxies catalog observed by the Sloan Digital Sky Survey is indirect evidence of the phenomenon of baryon acoustic oscillations, i.e., fluctuations on density of visible matter. This master's project aimed to study the fundamentals of cosmology from the baryon acoustic oscillations, to analyze the origin of this phenomenon, the theoretical prediction and how to measure its observables - correlation function and power spectrum. The final result of this work was the creation of a pipeline to make estimates of galaxy-bias and cosmological parameters from the measurements of galaxy angular power spectrum coefficients, whose results agree with the values of the fiducial model of the simulated catalog MICE (AU) | |
