It has been known for long that some of these massive black holes eject spectacular
plasma jets at a near speed - of - light that can extend far beyond the confines of their host galaxy.
Steve: Check our JR Minkel's recent article on
plasma jets at http://www.snipurl.com/26dun-sciam1 and to see some nifty Plasma sims that Blandford used in his talk at the American Physical Society meeting, see JR's blog item at http://www.snipurl.com/26dv2-sciam2

That model assumes that relativistic
jets store energy primarily in the form of hot matter (
plasma) and less in the form of magnetic fields generated by shock waves
at the front of the
jets.
«We have made, by far, the most precise extraction to date of a key property of the quark - gluon
plasma, which reveals the microscopic structure of this almost perfect liquid,» says Xin - Nian Wang, physicist in the Nuclear Science Division
at Berkeley Lab and managing principal investigator of the
JET Collaboration.
In this new work, Wang's team refined a probe that makes use of a phenomenon researchers
at Berkeley Lab first theoretically outlined 20 years ago: energy loss of a high - energy particle, called a
jet, inside the quark gluon
plasma.
Roger Blandford is the coauthor of the Blandford - Znajek Process, the leading explanation for how black holes produce
jets of
plasma traveling
at near light speed, but what's
plasma?
But there are two
jets — one that goes up and one that goes down — and these are associated with the region very close to the black hole and those
jets contain
plasmas that are moving
at relativistic speeds, that is to say, speeds close to that of light.
Even protostars — these are young stars that are just forming and making their own planetary disks and so on — they make very powerful outflows called, the same sort of
jets obviously moving
at slower speeds, but they are full of
plasma, that is flowing out
at high speed; white dwarfs, neutron stars, black holes big and small, they seem able to do this task, it really seems to be a very common phenomenon.
«Novel
plasma jet offshoot phenomenon explains blue atmospheric
jets: Physicists identify mysterious right - angle side -
jet occurring off the
plasma arc in air
at ambient pressure conditions.»
Astronomers using the National Science Foundation's Very Long Baseline Array (VLBA) have discovered
jets of
plasma blasted from the cores of distant galaxies
at speeds within one - tenth of one percent of the speed of light, placing these
plasma jets among the fastest objects yet seen in the Universe.
Scientists from the Massachusetts Institute of Technology, the University of Cambridge and some other international institutions investigating this «extreme stellar output» observed
jets of hot
plasma and gas bubbles (
at about 10 million degrees) blasting out from the galaxy's central black hole.
Using high - intensity lasers
at the University of Rochester's OMEGA EP Facility focused on targets smaller than a pencil's eraser, they conducted experiments to create colliding
jets of
plasma knotted by
plasma filaments and self - generated magnetic fields.
