Description of the research topic:

Einstein equations are famously complex and hard to find analytic solutions that satisfy them. Thiy may be reason that current cosmological models asuume the Universe to be homogeneous and isotropic. This may be tru on extremely large scales, but up to the limits we can observe, the distribution of matter is inhomogeneous, galaxies are clumped into large clusters, filaments and walls and there are huge voids between them. During the PhD we will continue our exploration if the inhomogeneity of matter distribution has a significant effect on the evolution history of the Universe (see: https://arxiv.org/abs/1607.08797). Depending on the background and interest of the candidate, (s)he can work on theoretical aspects, develop numerical simulations and/or conforont the model with cosmological observations.
