One of the most popular theoretical aspects of nowadays cosmology is the behavior of gravity on large scales. Galaxy clusters are the biggest gravitationally bound objects in our Universe and their properties can easily be predicted with simple formalisms. They are very massive, multi-component systems that consist of dark matter and baryons, and emit radiation almost across the entire electromagnetic spectrum. Therefore, galaxy clusters are extensively used to probe the evolution of the large scale structure formation and as a tool to test the standard cosmological models. Recent studies of the growth of galaxy clusters throughout the history of the universe agrees with the concordance Lambda Cold Dark Matter (CDM) model. They also help to understand how large scale structures (LSS) are formed from the seeded fluctuation generated at the very early stage of the universe. In this talk, I will present the cosmological information obtained from current and future studies of galaxy clusters, with focus on observations with the Sunyaev-Zel’dovich effect.
