Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles. Their new calculations reveal that pairs of ...

Dark matter, the most mysterious "stuff" in the universe, may be a sort of cosmic matchmaker, allowing supermassive black holes to overcome a final hurdle before colliding and merging into one.

In a new study, scientists from Canada have proposed a solution to the final parsec problem of supermassive black hole (SMBH) mergers using self-interacting dark matter. When two galaxies merge, gas ...

This particular pair, each more massive than 800 million Suns, lies in a galaxy 2.5 billion light-years away. The galaxy itself is a merger remnant — all that’s left after two galaxies, each hosting a ...
