Compact galaxies are small, high-density galaxies that have a significantly higher surface brightness compared to more typical galaxies. They are characterized by having a compact central region with a high concentration of stars, as well as a lack of extended spiral arms or other features commonly seen in larger galaxies. Research in the field of compact galaxies often focuses on understanding their formation and evolution processes, as well as their role in the overall population of galaxies in the universe. Studies may investigate the physical properties of compact galaxies, such as their stellar populations, dynamics, and morphology, as well as their interactions with other galaxies and the surrounding environment. Compact galaxies are of interest to astronomers because they can provide insights into the early stages of galaxy formation and evolution, as well as the physical processes that drive the growth and evolution of galaxies over cosmic time. They also offer a unique opportunity to study the conditions under which compact, dense stellar systems can form and evolve in different environments.
