Model of a Quasar
The accredition disk is shown in yellow, the green circle indicates a distance of 1 light year from the black hole at the center an area of high luuminosity. The blue circle indicates a distance of 100 light years marking the boundary of the gas cloud which contributes to the spectral lines. The Outer sphere indicates a distance of 100,000 light years marking the outer edge of the interstellar medium of the host galaxy.
The red cones represent the magnetized gas feeding the radio lobes.
The currently accepted model of a quasar places a spinning Black Hole at its center. This spinning action produces a "swirl of space" pulling gas streams in a spiral motion towards the hole. These gas streams collide as a result of the enormous gravitional energy, thereby creating intense friction and heating the disk. This is what gives a quasar its high luminosity.
This spinning action of the black hole, capturing the gases, creates a gyroscopic effect.
The effect of this is to hold the accredition disk in the same equitorial orientation near the center of the hole.
From the center of a quasar two oppositely pointed Jets emerge in the form of hot magnetised gas. These jets of gas eminating from the quasars central engine feed the radio lobes which can be picked up on earth by interferometers.
These jets form as fast thin streams of gas projecting outward in opposite directions for distances up to 1 million light years. The jets remain straight, due to the gyroscopic effect of the spinning black hole and accredition disk, indicating that their direction has remained constant over a considerable period of time.
