Bahcall-Wolf Singularity

The Bahcall-Wolf Singularity describes how stars near a supermassive black hole in a galaxy's center tend to form a dense, steady “cusp” over time. Gravitational interactions cause stars to exchange energy, leading those close to the black hole to cluster tightly, creating a predictable density pattern where star concentration increases as you approach the black hole. This process results in a specific density distribution that balances the gravitational pull of the black hole and the stars’ mutual interactions, forming a stable structure known as the Bahcall-Wolf cusp.
