The study of galaxy formation and evolution is concerned with the processes that formed a heterogeneous universe from a homogeneous beginning, the formation of the first galaxies, the way galaxies change over time, and the processes that have generated the variety of structures observed in nearby galaxies. It is one of the most active research areas in astrophysics.
Galaxy formation is believed to occur, from structure formation theories, as a result of tiny quantum fluctuations in the aftermath of the Big Bang. It is widely accepted that galaxy evolution occurs within the framework of a Λ Cold Dark Matter cosmology; that is to say that clustering and merging is how galaxies gain in mass, and can also determine their shape and structure.
