The role of group dynamics on the evolution of galaxies; observations and simulations

Abstract: The properties of galaxies are known to be largely influenced by their local and global environment. One of the important and unresolved aspects of structure formation is the prediction of the structural and dynamical properties of a virialized object, due to a large reflection of the nonlinear dynamics involved. In reality, galaxies plunge into galaxy groups and clusters, and their properties are affected by their environments.  In this talk, I am going to show the role of group dynamics on the evolution of galaxies using observational surveys, semi-analytic models, and hydrodynamical simulations for galaxy formation to improve the galaxy-halo connection scenario.  Furthermore, I will present the first result of tracking the evolution of galaxies with considering the different distance to the skeleton in which help us to understand how galaxy morphology, ages, gas fractions, and star formation rates are observed to steadily transform with environmental density across the cosmic web.
