Echoing Light Shows That Dark Matter May Gather Around Supermassive Black Holes

The way that dark matter is distributed may need a rethink. New research shows that dark matter could gather near supermassive black holes. The evidence is based on a new detection method, and is only moderately convincing so far. But if true, it also turns SMBH into 'dark matter labs' and could change how we understand SMBH growth.
