Cosmic plasma jets accelerator

The announcement from Stanford University National Accelerator Laboratory is Tangled magnetic fields power cosmic particle accelerators.

Astrophysical jets accelerated by electromagnetic plasma forces, the observed electrical excitation of elements and particles including creating synchrotron radiation, has previously been proposed by the Electric Universe theory.

Electric Magnetic plasma Universe

SLAC researchers have found a new mechanism that could explain how plasma jets emerging from the center of active galaxies, accelerate particles to extreme energies. Computer simulationsshowed that tangled magnetic field lines create strong electric fields in the direction of the jets, leading to dense electric currents of high-energy particles streaming away from the galaxy.

The simulations showed that when the helical magnetic field is strongly distorted, the magnetic field lines become highly tangled and a large electric field is produced inside the jet. This arrangement of electric and magnetic fields can, indeed, efficiently accelerate electrons and protons to extreme energies. While high-energy electrons radiate their energy away in the form of X-rays and gamma rays, protons can escape the jet into space and reach the Earth’s atmosphere as cosmic radiation.

“The mechanism that creates these extreme particle energies isn’t known yet,”… “But what exactly happens when the magnetic fields become distorted, and could this process explain how particles gain tremendous energy in these jets?

Relativistic magnetized plasma jets

Relativistic magnetized jets from active galaxies are among the most powerful cosmic accelerators, but their particle acceleration mechanisms remain a mystery. We present a new acceleration mechanism associated with the development of the helical kink instability in relativistic jets, which leads to the efficient conversion of the jet’s magnetic energy into nonthermal particles.

Large-scale three-dimensional ab initio simulations reveal that the formation of highly tangled magnetic fields and a large-scale inductive electric field throughout the kink-unstable region promotes rapid energization of the particles. The energy distribution of the accelerated particles develops a well-defined power-law tail extending to the radiation-reaction limited energy in the case of leptons, and to the confinement energy of the jet in the case of ions. When applied to the conditions of well-studied bright knots in jets from active galaxies, this mechanism can account for the spectrum of synchrotron and inverse Compton radiating particles, and offers a viable means of accelerating ultra-high-energy cosmic rays to 1020 eV.

If it is a Magnetic Universe full of ionised plasma, could it be electrical in nature?

Compared them to astrophysical observations

Good scientific and astronomical theories predicts. Natures particle acceleration by electromagnetic plasmas is now looking to be a successful prediction by and for the Electric Universe. Perhaps also for plasma cosmology.

the researchers simulated the motions of up to 550 billion particles – a miniature version of a cosmic jet… Then, they scaled up their results to cosmic dimensions and compared them to astrophysical observations…

“We see that a large portion of the magnetic energy released in the process goes into high-energy particles, and the acceleration mechanism can explain both the high-energy radiation coming from active galaxies and the highest cosmic-ray energies observed,” Alves said…

Next, the researchers want to connect their work even more firmly with actual observations
