New Supercomputer Simulations Show How Plasma Jets Escape Black Holes

The researchers used one of the most powerful supercomputers to better understand how a high-energy plasma flux flows away from the gravitational black hole that flows all its way, including light.

The boxes and other issues cross the backdrop of the black hole, the limit known as the "horizon event", and consume black holes under the rotation of the black hole. The question of a physicist over the decades was how some energy fled the process and focused on the plasmodic currents that travel around the space of light.

As defined in a paper published last week Letters on physical opinionResearchers from the Department of Energy and the University of California Berkeley performed a supermarket at the DoE Lawrence Berkeley National Laboratory to simulate electric charge charged electricity from the electrical plasma.

The simulation ultimately combined theories of the two decades ago to explain how to draw a rotating black hole.

The first theory relates to the electric currents around a black one and how it screws its magnetic field, known as Blandford-Znaj's mechanism. This theory will get the material captured in the gravity that rotates in black holes to reach future horizons. The black hole is like a massive rotary that rotates in a giant magnetic field, which will generate the voltage (energy) between the black hole and its equator. This energy difference is placed on the black holes at the poles.

The other theory described the Penrose process, split particle split horizons on the black hole. In this scenario, half of the particle is outside the black hole and the other particle produces negative energy and falls into black holes.

"It's a region that rotates black circles, called the Ergosphere, in which all the particles are forced into the same direction as the black hole", told Kyle Parfrey, the lead author of the paper and the theoretical NASA astrophysician. "In this area, it is possible that a particle is somewhat negative energy, if it tries to orbit against the rotation of the hole."

In other words, if half of the fractional fraction enters into the black hole, the angular momentum or rotation of the black hole will be reduced. But rotary energy must go somewhere. In this case, the other half of the part becomes an energy away from the black hole.

According to Parfrey, part of what was observed in their simulations in the Penrose process was somewhat different from one classical particle distribution to another. More than the distribution of particles, plasma particles cause electromagnetic forces loaded, some of which impulse the rotation of the black hole with the negative energy path. In that regard, Parfrey told me that Penrose is still a kind of process.

Parfrey's amazing part of the simulation told me: it was to establish a link between the Penford process and the Blandford-Znajek mechanism.

In order to generate magnetic fields that generate black hole energy in the mechanism of Blandford-Znaj, the electric current induced by particles is required, and the number of these particles has been the negative energy characteristic of the Penrose process.

"So, in some cases, it seems that at least two mechanisms are linked," said Parfrey.

Parfrey and his colleagues hope their models will provide a convenient context for horizons of telescope events that make up plasma jets that directly represent a series of telescopes. Until the first figure, however, Parfery said that he and his colleagues wanted to improve these simulations so that observations are better suited to date.
