Barred galaxies are a type of spiral galaxy characterized by a central bar-shaped structure composed of stars. These bars are thought to play a crucial role in the dynamics of galaxies, influencing their formation, evolution, and internal structure. Research on barred galaxies often focuses on understanding the formation mechanisms of bars, their effects on the overall morphology and dynamics of galaxies, and their relationship to other galaxy properties such as star formation and black hole growth. Barred galaxies are found in a wide range of environments and are a common type of galaxy in the universe.
