Main research activities/topics/projects

Clusters of galaxies are well known to be highly sensitive probes of cosmology through their number counts as a function of mass and redshift, and their clustering properties. The advent of the new generation of cluster surveys at different wavelengths opens the possibility of using clusters to constrain (or reveal) possible deviations of gravity from General Relativity at cosmological scales. Within this framework, the PhD student will collaborate with our research group on cluster cosmology. The project will be developed in the two following steps: (a) modification of the already available cluster cosmology pipeline to include the treatment of the Coupled Dark Energy and f(R) class of Modified Gravity (MG) models; (b) application to publicly available cluster surveys (e.g., SDSS, DES/yr1). The host research team is active part of the Euclid Consortium. Therefore, this work will represent the starting point for the derivation of constraints on MG from the cluster survey to be provided by the Euclid satellite.
