Physicists trace first runaway black hole to violent merger

Researchers have pieced together the violent merger that ejected a supermassive black hole from its host galaxy at nearly 1,000 kilometers per second, marking the first observed case of a phenomenon long predicted by general relativity.

Scientists detect black hole event horizon’s ‘fingerprints’ for first time

Scientists have detected the direct imprint of a black hole's event horizon in gravitational wave data for the first time, extracting information from closer to the "point of no return" than any previous observation. The findings, published Wednesday in Nature,…

UK quantum sensor clears key hurdle in dark matter search

Researchers at Imperial College London have demonstrated for the first time that a prototype quantum sensor can cancel out overwhelming laser noise by comparing two atom interferometers, recovering faint signals that would otherwise be lost. The advance, published in Nature…
