Black hole in Milky Way center seems powerful particle accelerator




The black hole at the center of the Milky Way appears to be responsible for cosmic rays flying through space with high energy. The petadeeltjesversneller at the center of our Milky Way, making it one hundred times more powerful than the CERN particle accelerator, the LHC.

An international team of scientists from the HESS consortium, or the High Energy Stereoscopic System coupled Cherenkov -telescopen in Namibia, giving the explanation for the galactic particle accelerator in Nature . Cherenkov-telescopes have been specially designed for the detection of gamma rays with collisions of particles in the atmosphere. Gamma rays itself the surface ie not achieve. The telescopes detect the so-called Cherenkov radiation emitted by the particles as they slow down in the atmosphere.

Researchers already detect a century cosmic particles that collide with the atmosphere of the Earth with high energy. For most of the particles, it is not possible to find out what the source is. This is due to the electric charge of the particles, causing them to be deflected by magnetic fields in the space. Gamma radiation is not affected by magnetic fields and therefore travels in a straight line from the source and which thus appears to consist of the big black hole in the center of the Milky Way.

The presumption that the radiation came from somewhere in the center of the Milky Way, existed a decade, writes the University of Amsterdam on his site. Ultimately, it is used data, collected in the last ten years by HESS together with enhanced data-analysis methods. The radiation could come from various sources, but which up till now was not clear. Suspected sources were supernova remnants, clusters of massive stars and the black hole at the center of the Milky Way.

Now it appears that it is indeed the black hole. The black hole accelerates particles as if it were a petadeeltjesversneller. In comparison with the LHC the accelerator is about one hundred times more powerful. The LHC allows particles thirteen teraelektronvolt collide.
