Astronomers believe that supermassive black holes play a fundamental role in regulating star formation. And they are now providing evidence of this with a cluster of galaxies that are outrageous stars. A cluster of galaxies whose central supermassive black holes run out of fuel.
Theare our largest structures . For these clusters, which is the core of their central galaxy are real sources of . But what happens when these black holes become inactive? This is the question that researchers have asked themselves. And especially thanks to the information from ( ) they now give an answer.
Remember thatconsists of hundreds, if not thousands of galaxies, maintained by and was invaded by a hot emitting . In their heart is the activity of one generally prevents this gas from cooling and forming in numbers. This is the case in many clusters relatively close to ours .
A year ago, the SpARCS1049 cluster – or SpARCS104922.6 + 564032.5 would be complete – which stands at about 9.9 billionof our earth, in , had already shown Place and , he to one Fantastic. About 900 per year. That’s 300 times more than in our galaxy. All this takes place about 80,000 light-years from the center of the cluster, outside the galaxies that form it.

A black hole runs out of fuel
The reason ? “When the cat is gone, the mice will play”, explains Julie Hlavacek-Larrondo, researcher at the University of Montreal (Canada) ia. In fact, SpARCS1049 shows no signs of activity from a supermassive black hole in its central galaxy. There is no evidence of a throw escapes from another black hole radio or X-ray source indicating that the material was heated while falling against a black hole.
Thus, the supermassive black tower in SpARCS1049 no longer seems to be active. He stopped feeding his environment with energy. As a result, the gas surrounding the galaxies could cool enough for stars to begin forming almost sincerely. ” Manythought that without the intervention of a black hole, star formation would come out of hand, reminiscent of Tracy Webb. Now we have proof. “
Why is this black hole so quiet? This is the next question. ONEcould have moved the denser gas away from the cluster’s central galaxy. The result: the supermassive black hole in the center of this galaxy is simply running out of fuel.
