Initial conditions of the universe : signatures in the cosmic microwave background and baryon acoustic oscillations.
In this thesis, we investigate the signatures of isocurvature initial conditions in the cosmic microwave background (CMB) through the temperature and polarization anisotropies, and in the large-scale structure distribution ...
Optimisation of the population Monte Carlo algorithm : application to cosmology.
In this thesis we study the Population Monte Carlo (PMC) algorithm and utilise simulations to improve the efficiency of the algorithm by optimising the algorithm parameters. We then ap ply these optimisation results to ...
Non-circularity of beams in the CMB polarization power spectrum estimation.
Precise measurements of the Cosmic Microwave Background (CMB) anisotropies have been one of the foremost concerns in modern cosmology as it provides valuable information on the cosmology of the Universe. However, an ...
