Twin jets pinpoint the heart of an active galaxy
Two particle jets shoot out from the heart of active galaxy NGC 1052 at the speed of light, apparently originating in the vicinity of a massive black hole. Researchers have now measured the magnetic fields in this area. They observed the bright, very compact structure of just two light days in size using a global ensemble of millimeter-wavelength telescopes. The magnetic field value recorded at the event horizon of the black hole was between 0.02 and 8.3 tesla. The team concludes that the magnetic fields provide enough magnetic energy to power the twin jets.
