The study adds ten new BBH mergers to existing catalogs and provides further evidence for the significance level of previously identified events. The new events display interesting new features that include unexplored ranges of the effective spin and mass ratio, they challenge aspects of stellar collapse models, and have implications for BBH formation channels and black hole mass gaps.

Researchers were able to use the unique subtle flickering of the bright glow of orbiting gas to construct the most accurate model to date of our own galaxy's central black hole, providing insight into properties such as its structure and motion.

Looks can be deceiving. The light from an incandescent bulb seems steady, but it flickers 120 times per second. Because the brain only perceives an average of the information it receives, this flickering is blurred and the perception of constant illumination is a mere illusion.

Black holes are the densest, most mysterious objects in the universe. These super-compressed objects are millions or billions of times larger than our own Sun, with gravitational pulls so great that not even light can escape. But not all black holes are created equal. Some are larger than others and, while they all absorb the […]
