Astrophysicist spoke about an unknown signal from the center of the Milky Way

The unusual signals from the center of the Milky Way, recorded by scientists with the ASKAP CSIRO radio telescope in Western Australia, are unlikely to belong to intelligent life forms. This opinion was shared with Rambler by an astrophysicist, Doctor of Physical and Mathematical Sciences, a leading researcher at the Institute of Nuclear Physics of Moscow State University, Alexander Panov.

“This is very unlike an artificial signal. This signal has a continuous spectrum. An artificial signal cannot look like that, because it is very inconvenient to transmit any information in this way. Artificial signals will have a different spectrum.”

He noted that this kind of signal is typical for pulsars and magnetars – two types of neutron stars with strong gravity and powerful radiation.

“It is difficult to say anything definite yet. Strong polarization, which changes over time, indicates the presence of a strong magnetic field in the emitter, which is typical for the magnetospheres of pulsars and magnetars.”

According to Panov, the variability of the signal recorded by astronomers may be associated with unusual conditions of accretion, that is, the gravitational increment of material in the celestial body that emits this signal.

“The variability can be associated with the accretion of matter, and, perhaps, some rare conditions of accretion have just developed, why such sources have not been encountered before. But further observations are required, perhaps something will become clearer.”

The astrophysicist clarified that such variability can occur when a large celestial body attracts smaller ones. Thus, the signal arises in the process of absorbing a smaller body, then it is interrupted, and then reappears when a new small body is attracted.

“This usually happens in binary systems. For example, there is a neutron star, and an ordinary star flies nearby, from which some substance flows into the neutron one. It does this, relatively speaking, in portions, so that the signal appears and then fades out again.”

The Astrophysical Journal on October 12 published an article according to which scientists using the ASKAP CSIRO radio telescope located in Western Australia recorded an unusual signal from the center of the Milky Way.

Their attention was attracted by the unusual periodicity of the signal emitted by an unknown celestial body. The object was at first invisible, then appeared in the field of view of the radio telescope, then faded out again. It has been codenamed ASKAP J173608.2-321635. Currently, the study of this phenomenon continues.
