Galaxy associations are groups of galaxies that are physically close to each other and share similar properties. These associations can include various types of galaxies, such as spiral galaxies, elliptical galaxies, and irregular galaxies. They often interact through gravitational forces, which can lead to phenomena like galaxy mergers or the formation of new stars. These associations are important for understanding the large-scale structure of the universe. By studying galaxy associations, astronomers can learn about the distribution of dark matter, the evolution of galaxies, and the dynamics of cosmic structures. This research helps to paint a clearer picture of how galaxies form and evolve over time.
