Description

Using state of the art numerical simulations, I have unravelled observational signatures of several alternative cosmological models in the large-scale structure of the cosmic web. The key observational probe under study is evolution of cosmological voids, to provide us with clues to the underlying cosmology of the Universe. While the ultimate goal will be to include galaxy formation recipes to determine the true efficacy of using cosmic voids in realistic future surveys with the next generation of ground- and space-based telescopes, in this presentation I will reveal how the size, shapes and density of voids, and their evolution through cosmic time, depend on the underlying cosmology of the Universe, showing that universes with an evolving and decaying dark sector leave a significant imprint on the void structure when compared to the standard Lambda Cold Dark Matter cosmology.
