What Does IGM Stand For?
IGM stands for InterGalactic Medium
IGM, or InterGalactic Medium, refers to the matter that exists in the vast spaces between galaxies. Composed primarily of hydrogen and helium, along with trace amounts of heavier elements, the IGM plays a crucial role in the overall structure and evolution of the universe. It serves as a medium for various astrophysical processes, including the formation of stars and galaxies, and contributes to our understanding of cosmic phenomena and the large-scale behavior of the universe.
