Description
Galaxy clusters are excellent natural laboratories to study the nature of gravity and test possible alternative to the Concordance Model, at the edge between cosmology and astrophysics. I present recent results obtained by using the updated version of MG-MAMPOSSt, a code that reconstructs the mass distribution of clusters with kinematics and lensing analyses in modified gravity/Dark Energy frameworks. I will show the constraints that can be placed on the parameter space of viable modifications of the LambdaCDM scenario, as well as on the distribution of dark matter down to the cluster core, using high quality imaging and spectroscopic data, highlighting the strength and limitations of the method as well as future lines of investigation.
