Resumen:

We describe how an exact solution of Einstein's equations (the Szekeres models) can be used to construct assorted configurations of multiple non-spherical self-gravitating cold dark matter structures (over-densities and voids) that evolve from realistic initial data. Since the dynamical freedom of the Szekeres models allow (under certain restrictions) for placing these structures in previously specified locations, we are able to provide a fully relativistic non-perturbative coarse-grained description of actually existing cosmic structure at various scales. We believe that there is an enormous range of potential applications of this work to current astrophysical and cosmological problems. © 2017 by World Scientific Publishing Co. Pte. Ltd.
