Answer to Question 1

High-energy jets appear to be the result of matter flowing into a supermassive black hole in the nucleus of an active galaxy. Conservation of angular momentum forces the matter to form a whirling accretion disk around the black hole. How that produces jets shooting away perpendicular to the disk is not entirely understood, but it appears to involve magnetic fields that are drawn into the accretion disk and become tightly coiled, storing energy sufficient to eject high-temperature gas. The twisted magnetic field confines the jets in a narrow beam and causes synchrotron radiation.

Answer to Question 2

False
