Why are the jets from radio galaxies compelling evidence that black holes power active galactic nuclei?
A) their extreme luminosity
B) their relativistic speed
C) their compact bases
D) all of the above

Question

Quizplus · Accepted Answer

The jets from radio galaxies exhibit all of the listed properties - extreme luminosity, relativistic speed, and compact bases - which are consistent with the theory that black holes power active galactic nuclei. The jets are thought to be generated by the strong magnetic fields associated with the black holes, which accelerate charged particles to near-light speeds and cause them to emit synchrotron radiation. This explains the observed brightness, speed, and morphology of the jets.
