How are relativistic jets formed?
Relativistic AGN jets are formed when the black hole spins and the the accretion disk is strongly magnetized, perhaps on account of gas accreting at high latitude beyond the black hole sphere of influence.
AGN jets are collimated close to the black hole by magnetic stress associated with a disk wind..
How do relativistic jets escape black holes?
Although the mechanism by which the jets are produced is not completely understood, the process likely involves the acceleration of matter near the poles of the black hole and an interaction with the tangled magnetic field in the region near the poles of the accretion disk..
Is an astrophysical jet the same as a relativistic jet?
An astrophysical jet is an astronomical phenomenon where outflows of ionised matter are emitted as extended beams along the axis of rotation.
When this greatly accelerated matter in the beam approaches the speed of light, astrophysical jets become relativistic jets as they show effects from special relativity..
What are the relativistic jets of Blazars?
Relativistic jets of active galactic nuclei have been known to exist for 100 years.
Blazars with their jet pointing close to our line of sight are some of the most variable and extreme objects in the universe, showing emission from radio to very-high-energy gamma rays..
What galaxy has relativistic jets?
9-2343, located 656 844 372 light years away, has now been classified as a giant radio galaxy that is 4 million light years across and happens to have a blazar in its core; a blazar is an active galactic nucleus (AGN) with a relativistic jet (a jet travelling close to the speed of light) directed towards an observer..
What is a relativistic jet?
Relativistic jets are beams of ionised matter accelerated close to the speed of light.
Most have been observationally associated with central black holes of some active galaxies, radio galaxies or quasars, and also by galactic stellar black holes, neutron stars or pulsars..
Why do black holes have relativistic jets?
If the black hole is spinning, it drags on the field, winding it into a tight cone at the rotational poles of the black hole.
It is this twisted field that accelerates particles away from the black hole as jets and, in the process, extracts energy from the rotation of the black hole..

- A black hole can launch a powerful relativistic jet after it tidally disrupts a star.
If this jet fortuitously aligns with our line of sight, the overall bright- ness is Doppler boosted by several orders of magnitude. - If the black hole is spinning, it drags on the field, winding it into a tight cone at the rotational poles of the black hole.
It is this twisted field that accelerates particles away from the black hole as jets and, in the process, extracts energy from the rotation of the black hole. - These jets are believed to be the sources of the fastest-travelling particles in the Universe -- cosmic rays.
In some cases these jets can reach outside of the galaxy itself, ending in giant radio lobes far from the active galaxy center.
