Question 1 (2 points) Twisted magnetic fields are believed to be responsible for both acceleration and collimation of AGN jets. O True O False Save Question 2 (2 points) The "Thot spots" produced by a powerful radio galaxy are caused by O impact of jets on the inter-galactic medium O a pair of black holes shot out of the center of the galaxy O thermonuclear explosions of massive stars O gas falling onto the magnetic poles of a central black hole Save Question 3 (2 points) Superluminal motion" of jet structures on the sky results from the jet moving exactly towards the observer O the jet moving almost but not exactly towards the observer O the expansion of the Universe O the combined velocities of the moving gas and the light it emits

Explanation / Answer

Question 1::

True that twisted magnetic fields are believed to be responsible for both acceleration and collimation of active galactic nucleus (AGN) jets.

Explanation::

In powerful AGN jets are neither gas pressure nor radiation pressure appears to be adequate to the task of collimating large momentum flux. This leaves magnetic field as the prime source.
