Why is space-based VLBI scattering sub-structure "Hopefully, a new promising tool to reconstruct the true image of observed background target(s)"?
It is well known that the study of pulsars is hampered by the scattering effect - the distortion of radiation during the passage of the interstellar medium. Even very compact pulsars look like lanterns in fog. It is clear that this effect should be observed when studying not only pulsars, but also other radiation sources. And here Radioastron plays its role. The pulsar, like a lighthouse, illuminates the Galaxy, and the interstellar medium, like fog, blurs its image. &quot;Radioastron&quot;, in turn, &quot;filters&quot; this radiation. It turned out that against the background of blurry images of objects in the Universe, there are ultracompact specks - a scattering substructure. Accordingly, the effect of the fine structure of scattering discovered thanks to the space interferometer will help to understand the nature of the turbulence of the interstellar medium, to determine the distance to the clouds, causing scattering of radio waves. This is a significant contribution to astrophysics and is interesting in itself. Today we already have a better understanding of the physics of turbulent flows in the interstellar medium. And most importantly, if we do not correctly interpret the results of studying the Universe, we will be able to correctly interpret the results of observations.
At the center of our Galaxy is a massive black hole - about 10 million
times heavier than the Sun. It is simply necessary to study it, but
scattering of radiation interferes with it. Note that the study of
black holes in modern astrophysics is one of the fundamental,
fundamental problems. Scientists solving them now know about the
effect of scattering substructure discovered by us and take it into
account in their works. Moreover, having obtained a true picture of
the spots of the scattering substructure, it is possible to restore
the true image of the object hidden from us behind the scattering
screen. This opens up tremendous opportunities for astrophysicists.
There are already results: a significant number of publications have
appeared in leading scientific journals describing observational data
on the scattering substructure and mechanisms for reconstructing true
images of space objects.
