The flow of black hole radiation prevents

An international team of scientists, with Spanish participation, has quantified the relationship between star formation rate and the power generated by black holes in centers of galaxies. The study, published this week in the journal Nature, comes a time when the flow of black hole radiation prevents the formation of more stars.The blue dots correspond to active galaxies, emitting X-rays detected from the Herschel Space Observatory of ESA.

"The relationship between these two factors suspected for years, but in this work we have clearly identified for the first time," said Dr. Antonio SINC Cava.One of the most energetic phenomena in the universe is the growth of a black hole. In the center of the galaxy emits radiation that dominates the observable generated by stars at almost any wavelength. For measuring the star formation, scientists have analyzed the sky in wavelength sub-millimeter from the Herschel Space Observatory of the European Space Agency.
