Galactic filaments are vast, thread-like structures in the universe that form part of the cosmic web. They consist of dark matter and gas, connecting clusters of galaxies and influencing their formation and movement. These filaments can stretch for millions of light-years and are crucial for understanding the large-scale structure of the universe. The study of galactic filaments helps astronomers learn about the distribution of matter in the universe. They are often found in regions where galaxies are densely packed, such as in the vicinity of galaxy clusters. Observing these filaments can provide insights into the evolution of the universe and the behavior of dark matter.
