But if you have clusters of black holes at the centers of galaxies, there are mechanisms by which some could rapidly grow, form binaries and merge with each other.»

In computer simulations, the researchers show that a black hole can rapidly grow at the center of its host galaxy if a nearby galaxy emits enough radiation to switch off its capacity to form stars.

Astronomers have long predicted the existence of black holes larger than those formed from single stars, but smaller than the million or billion solar mass ones lurking at the centers of galaxies.

Astronomers have seen them shooting out of young stars just being formed, X-ray binary stars and even the supermassive black holes at the centers of large galaxies.

This may help solve such mysteries as how gas clouds are triggered to form new stars and when the massive black hole at the center of every mature galaxy forms.

Maunakea, Hawaii — Stars forming in galaxies appear to be influenced by the supermassive black hole at the center of the galaxy, but the mechanism of how that happens has not been clear to astronomers until now.

The halos around quasars — the brightest and the most active objects in the universe, they are galaxies formed less than 2 billion years after the Big Bang; they have supermassive black holes in their centers and consume stars, gas, interstellar dust and other material at a very fast rate — are made of gas known as the intergalactic medium and extend for up to 300,000 light - years from the centers of the quasars.

Black holes that form due to the collapse of massive stars typically have masses 5 - 20 times that of the sun, but supermassive black holes — found in the centers of nearly all known sizeable galaxies — are far bigger, at about hundreds of thousands, or even billions, of solar maBlack holes that form due to the collapse of massive stars typically have masses 5 - 20 times that of the sun, but supermassive black holes — found in the centers of nearly all known sizeable galaxies — are far bigger, at about hundreds of thousands, or even billions, of solar mablack holes — found in the centers of nearly all known sizeable galaxies — are far bigger, at about hundreds of thousands, or even billions, of solar masses.

From supermassive black holes at galactic centers to giant bursts of star formation to titanic collisions between galaxies, these discoveries allow astronomers to probe the current properties of galaxies as well as examine how they formed and developed.

This is the glowing accretion disk of gas that can form around a supermassive black hole at the center of an otherwise ordinary galaxy.
