Echo mapping technique reveals hints of dark matter clusters around supermassive black holes

Summary

Astronomers using a technique called echo mapping have found evidence suggesting that supermassive black holes, including Sagittarius A* at the center of the Milky Way, may be surrounded by dense clouds and clusters of dark matter. The research could provide new insights into the nature of dark matter, which outweighs ordinary matter by a five-to-one ratio but remains invisible as it doesn't interact with electromagnetic radiation. The findings hint at extra material around black holes that cannot be explained by the black hole alone.
