Abstract

In this project we will study the detection and use of cosmological voids, i.e. large empty spaces of low density in the universe. The Main focus will be the study, implementation and improvement of specific detectors, especially those who work in real galaxies catalogs.In addition, we will study their properties, e.g. abundance and profiles, and how they can be used to constraint cosmological parameters and modified gravity theories. We will also have a theoretical study and detailed numerical implementations of the different void properties. (AU)
