Shed light on the brightest objects in the universe

The Dartmouth team of astrophysicists discovered the extent to which the quasars and black holes can influence their own galaxy.

The team plans to publish an article in Astrophysical Journal, which details made ​​the discovery and research based on the constant lookout for 10yu quasars. Researchers have documented enormous capacity for radiation from quasars, which reach for many thousands of light-years distant, even beyond their own galaxies.

"For the first time, we can assess the real extent to which these quasars and black holes affect their galaxy and we see that they are limited only by the amount of gas in the galaxy," said researcher - Dartmouth havin. "The radiation effect on the gas up to the most outlying galaxies and disappears only when it decreases the amount of gas."

"It's interesting, because we know from a number of different independent variables that quasars have a huge impact on the galaxies in which they live," said another researcher of this team - Hickox. "There is a lot of debate about how they actually affect the galaxy, but now we have one common aspect of the interaction, which can help to continue the research on the scale of such galaxies. No one previously did not know about such a large spread of radiation from quasars and black holes in galaxies within them. "
