Don't let the name fool you. Black holes might all have hearts of pure darkness, but many cloak themselves in rings of fire that blaze like little else in the cosmos. That doesn't mean all are ...

Jets from black holes trigger cooling in the hot gas, causing it to condense into warm filaments. These filaments then flow toward the black hole, feeding it, and the cycle repeats. Brightness ...

Core package to analyze gravitational-wave data, find signals, and study their parameters. This package was used in the first direct detection of gravitational waves (GW150914), and is used in the ...

At first glimpse, it may seem like infant stars and supermassive black holes have very little in common. Infant stars, or "protostars," haven't yet gathered enough mass to trigger the nuclear ...

Space experts have uncovered a massive swarm of new supermassive black holes that could blow theories about galaxies wide open. A team of scientists using data from two NASA telescopes revealed ...
