Center of the galaxy like a giant accelerator.

<P Align=center> </ P> <CENTER> imagine the Milky Way spiral arms and around the map </ CENTER> According to the Russian Space News reported that U.S. scientists recently announced that the black hole at the galactic center is like a giant accelerator ., constantly throwing around high-energy gamma-ray space. .The study by the University of Arizona, Los Alamos National Laboratory and the University of Adelaide scientists jointly made. .According to measurements, the galactic center black holes emit high-energy particles with energy up to hundreds of thousands of electron volts. .Scientists made in accordance with the latest theories, like the black hole at the galactic center of the universe is a gigantic particle accelerator, will continue to accelerate protons to very high speed and high-energy gamma rays released. .According to the scientists calculate, after the accelerated protons with energy up to 100 trillion electron volts. .In comparison, the world's most powerful accelerator, the power - "Large Hadron Collider," only to particle acceleration to 7 trillion electron volts of energy. .Australia by the University of Arizona professor 弗尔维奥梅 astrophysics research team led by time-consuming this theory put forward by several years, a clear picture of the black hole at the center of the galaxy near the physical processes that occur. .Scientists discovered in the course of the study, some powerful and chaotic magnetic field near the black hole is constantly protons and other charged particles accelerated to high energy. .In order to produce high-speed proton movement reflects the center of the model, the researchers also used a black hole 10 light years away from the interstellar gas within the scope of the detailed distribution maps. .By analyzing the distribution of the magnetic field, scientists have identified areas within the 220,000 figure the trajectory of high-energy protons. .The results show that even when the speed of protons close to the speed of light, their motion is still very confusing - often take time to fly 10 thousand light years away. .When these high-speed protons from the scope of the role of the black hole, they often with the surrounding interstellar hydrogen in the low-energy protons collide, and produce a very short life cycle of meson - will release its decay flying in all directions along the high-energy gamma .rays. .According to scientists, the calculation of the galactic center black hole at a distance of about 10 light years within the proton, only about 31% would produce gamma rays. .The remaining 69% will be flying long distances in until after the collision with the gas particles and produce gamma rays. .The researchers believe that their latest build of this model is very good picture of the galactic center black hole out of the release of gamma-ray map of the distribution and density. .</ P>.
