Despite its global homogeneity and isotropy, the local matter distribution in the late Universe is manifestly inhomogeneous. Understanding the various effects resulting from these inhomogeneities is one of the most important tasks of modern cosmology. In this thesis, we investigate two aspects of the influence of local structure: firstly, to what extent do local structures modify the average expansion of spatial regions with a given size, and secondly, how strongly does the presence of… Expand
