Unusual light signal yields clues about elusive black hole merger

8 enero 2015

Scientists have found what appear to be two supermassive black holes in the final stages of a merger, a rare event never seen before. The discovery could help shed light on a long-standing conundrum in astrophysics called the «final parsec problem,» which refers to the failure of theoretical models to predict what the final stages of a black hole merger look like or even how long the process might take.
