Researchers clarify dynamics of black hole rotational energy
(PHYSorg.com Space & Earth)

Astrophysicists at MIPT have developed a model for testing a hypothesis about supermassive black holes at the centers of galaxies. The new model enables scientists to predict how much rotational energy a black hole loses when it emits beams of ionized matter known as astrophysical jets. The energy loss is estimated based on measurements of a jet`s magnetic field. The paper was published in the journal Frontiers in Astronomy and Space Sciences.
