Astronomers have found located in the Crab Nebula pulsar is inexplicable from the point of view of modern theories of high-energy radiation
Scientists point out that before the pulsar, which is called PSR B0531 +21, the graph of the photon distribution of the radiation in the energy An "obrubanie" in the high-energy part of the spectrum from what astronomers have concluded that some of the radiation, particularly gamma rays not recorded with the device, writes Lenta.ru.
New research carried out by using a system of telescopes VERITAS, discovered a pulsar photons with energies above 100 GeV. For comparison, the photons of visible radiation from the sun have an energy of about 2 eV.
According to scientists, the existing models of pulsars can explain the existence of radiation with such a high energy. They note that additional observations to install a full range of pulsar radiation.
Neutron Star PSR B0531 +21 was formed as a result of a supernova explosion. Earth's inhabitants could watch it in 1054. The pulsar is located at a distance of 6400 light years from Earth, in the Crab Nebula, in the constellation Taurus.
Recall pulsar — a rapidly spinning it around its own axis neutron star with a very strong magnetic field. Its magnetic poles do not coincide with the geometric and are sources of radiation, which is distributed by a narrow cone. To the casual observer, such a star is pulsating like a flashing light object.
