Simulation shows how star collisions fuel massive black holes

It's difficult to predict with certainty what will happen when giant stars collide, but new, first-of-their-kind hydrodynamic simulations by the DEMOBLACK team at the University of Padova in Italy point to a range of exotic ...

Black holes and dark matter—are they one and the same?

Primordial black holes created in the first instants after the Big Bang—tiny ones smaller than the head of a pin and supermassive ones covering billions of miles—may account for all of the dark matter in the universe.

How did supermassive black holes form? What is dark matter? In an alternative model for how the universe came to be, as compared to the 'textbook' history of the universe, a team of astronomers propose that both of these ...

Video: A signal from beyond

UConn astrophysicist Chiara Mingarelli is part of a team of researchers who recently published data on a hint of a signal that sent ripples of excitement through the physics community. These monumental findings are the culmination ...
