  • Abstract:-
  • In the current picture of structure formation, galaxy clusters arise from rare high peaks of the initial density fluctuation field. These peaks grow in a hierarchical fashion through the dissipationless mechanism of gravitational instability with more massive halos growing via continued accretion and merging of low-mass halos. The abundance of galaxy clusters and their correlation function are powerful tools for constraining the cosmological parameters.
