Argentine astronomers conducted observations of a mysterious source of a very high energy gamma radiation, known as Hess J1857 + 026, and opened its nature. It turned out that powerful radiation is generated by a gigantic bubble of hot gas, within which the pulsar is located. The results of the study were published in the repository of preprints ARXIV.ORG.
Sources of gamma-radiation of very high energy emit photons with energy from one hundred gigailencelectrics up to one hundred teraelectronvolt. It is known that some sources are blusar or double systems with a compact object, however, the nature of most sources remains not known. One of them is Hess J1857 + 026 – an extended source of gamma radiation, which is 20,500 light years away.
The source includes a PSR J1856 + 0245 radio radiopulsary, which is shifted from the center about eight angular minutes. The recovery period of the pulsar is 81 millisecond, and its age, determined by the speed of slowing the rotation, reaches 21 thousand years. It slows down due to the release of 4.6 to 10 in the 36th degree of ERG per second. It was assumed that Hess J1857 + 026 is a plasteron, that is, a nebula, fed by the wind of the pulsar. According to another hypothesis, the source of gamma radiation actually represents two objects located at different distances on one ray of sight.
Astronomers conducted observations of the source of gamma radiation in the radioontinuum, that is, in a continuous spectrum of radio frequencies, using the VLA telescope complex (Karl G. Jansky Very Large Array). They did not find any evidence of the existence of reinforced radio emission characteristic of the Plearon. However, the researchers discovered a superproof at a distance of 18 thousand light years, which is comparable to the distance to the pulsar.
Superpunces are a giant sparse area of interstellar space that can reach tens and hundreds of thousands of light years in diameter. Unlike the Plemons, fueled by a single pulsar, superpoints get energy from massive and hot stars and from supernovae outbreaks inside them.
