Abstract

This research project is focused on the fields of galaxy clusters and cosmology. Regarding clusters the sub-projects I intend to carry on during the following two years can be divided in two branches: i) detection of new clusters and ii) study of the cluster properties. For the first branch the main goal is to produce new samples of high redshift clusters where evolutionary effects can be detected. The second branch is focused on deepening the understanding of the physics and interplay of their components (darkmatter, hot gas and galaxies). On cosmology I intend to keep my participation on the large surveys DES, Euclid and WFMOS, whose main goal is to quantify the dark energy density and its evolution but will also leave a huge legacy for all areas of the astrophysics. On the other hand these projects, due to their scope and generality, will leave a legacy for several astrophysics areas. (AU)
