Black holes continue to grow rapidly

Black holes - areas in space with a powerful gravitational pull that are inevitable even for objects moving at the speed of light - known for their brutal appetites. However, these "monsters" seem to be more gluttonous than previously believed.

Giant black holes, most of which (if not all) are hidden in the center of galaxies and increasing in size at an incredible rate.

Supermassive black holes are monstrously huge, their weight may exceed 10 billion times the mass of our sun. Using computer simulations, researchers have tried to follow the way black holes grow, they were interested in particular similar to the Milky Way spiral galaxy.

Astronomers have discovered that galaxies located at the centers of black holes, contrary to the conventional theory can grow actively absorbing the "galactic gas" and some other substances in the quiet of spiral galaxies. Previously, scientists believed that the increase in mass of the black hole is a result of the merger of the host galaxies.

Debatista Dr. Victor (Victor Debattista), head of research at the University of Central Lancashire (University of Central Lancashire) noted the following: "Black holes, as shown by our simulations, quickly grow in spiral galaxies. Simulation allows us to improve our understanding of the growth of black holes in galaxies of different types. "

The new study was confirmation of the fact that the black hole of the Milky Way is able to absorb for about 10 years in a matter of 15 Earth masses, after a meeting with the gas cloud, by moving to the very center of the galaxy.

Scientists theorize that a giant black hole is located in the Sombrero galaxy. Scientists estimate that it is now more massive than the Sun, 500 million times.
