Astronomers have discovered the fastest pulsar


American researchers in the field of astronomy, together with their colleagues from France gathered compelling evidence that an object INTEGRAL IGR J11014-6103, which has been found orbiting observatory, a pulsar, able to move with great speed. Details were presented in an article published recently in the journal Astrophysical Journal Letters.

During the observations of the INTEGRAL-galactic plane IGR J11014-6103 has been identified by scientists as a regular source of hard X-ray (20-100 keV) in the constellation Carina. Some time later, the area of the sky where he was, was thoroughly investigated telescopes XMM-Newton and Swift, after which the source was observed in the soft X-ray range. After processing all the data, the researchers found that IGR J11014-6103 has a complex structure with well-selected point X-ray emitter and a long "tail" and resembles more pulsar wind nebula.

In order to verify the accuracy of classifying findings, the US-French research team performed at the X-ray space telescope such as "Chandra" (with different angular resolution), additional research is IGR J11014-6103. The duration of these observations was only about a half hour.

Thus, the new images this point source is shown quite clearly, and its position in space is defined with incredible accuracy. While in search of the optical and infrared sources in the catalogs, any objects with similar coordinates authors were detected, suggesting the possibility of the pulsar nature of IGR J11014-6103: in these ranges pulsar radiation just needs to have a similar level of weakness.

In addition, the spectrum and the state of flux stability IGR J11014-6103, which was calculated by the comparative analysis of the recent data "Chandra" eight years ago with the data from XMM-Newton, were also suitable for the pulsar. If the point source is found in the IGR J11014-6103 is actually pulsar, as evidenced by all the available data, the X-ray "tail" appear to have formed since rapid movement in interstellar space. The axis of this "tail" should then pass directly through the start point, and here the researchers did not have long to wonder: right on the axis is located near the IGR J11014-6103 supernova MSH 11-61A, or rather its remains.
