A new form of black hole archeology, linking spin to gas and dust, has revealed that these cosmic titans spin faster than ...

The passing gravitational waves “stretch or contract the universe by around 20 meters [about 65 feet] or so,” says Matthew ...

"Unexpectedly, we found that they were spinning too fast to have been formed by galaxy mergers alone. "They must have formed in large part from material falling in, growing the black hole smoothly ...

"We have studied the giant black holes found at the centers of galaxies, from today to as far back as seven billion years ago," team member Logan Fries, from the University of Connecticut, said in a ...

By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, ...

Enabled by supercomputing, University of Pretoria (UP) researchers have led an international team of astronomers that has ...

Black holes and their archaeology The results of the SDSS Survey of mass measurements of hundreds of black holes were a surprise, according to Fries. That's because the spin rates reveal something ...

Gravitational waves are unlocking the origins of black holes, linking spin shifts to sequential mergers in star clusters.
