(Phys.org) —A team of space scientists working in Italy has found more evidence that suggests the energy needed to emit jets from supermassive black holes comes from the spin of the black hole itself. In their paper published ...
(Phys.org) —A pair of researchers, Tal Alexander of the Weizmann Institute of Science, in Israel and Priyamvada Natarajan with Yale University in the U.S. has come up with a possible explanation for the rapid growth of ...
(Phys.org) —Astronomers studying two classes of black-hole-powered galaxies monitored by NASA's Fermi Gamma-ray Space Telescope have found evidence that they represent different sides of the same cosmic coin. By unraveling ...

(Phys.org) —Researchers in Spain have discovered a black hole that doesn't reveal itself through x-ray radiation thrown off by material that is being sucked into it. In their paper published in the journal Nature, team ...
Supermassive black holes (those with millions to billions of solar-masses) are thought to reside at the centers of most galaxies. These black holes must have undergone periods of intense accretion activity to grow to their ...
