Galaxy formation
Galaxy formation refers to the processes by which galaxies emerge and evolve from initial density fluctuations in the early universe. It involves gravitational collapse, gas dynamics, star formation, and feedback mechanisms.
Galaxy formation is discussed in astrophysics, cosmology, and large-scale structure studies.
Status
Galaxy formation is studied through observations across cosmic time and through numerical simulations. Models seek to account for observed galaxy properties, distributions, and evolutionary pathways, and continue to be refined.
