Modelling quasi- and non-linear effects in the redshift space two-point correlation function

Current and future galaxy surveys will be used to measure baryonic acoustic oscillations (BAOs) with high significance. In this thesis, we study BAO anisotropies arising in the two-point correlation function (2PCF) of galaxy redshift space and we do so with a derivation of the configuration-space 2PCF using the streaming model (Peebles 1980; Fisher et al. 1994; Fisher 1995; Scoccimarro 2004). Following the approach discussed in Jeong et al. 2015 and applying the streaming model further developed in A. Taruya et al. 2010, we can exploit the non-linear anisotropies of BAOs in redshift space to extract the cosmological information contained in BAOs themselves.
