Using a system of wireless telescopes, Russian and American astronomers obtained a multi-frequency composite image of the TXS 0128 + 554 galaxy, a young nucleus that emits gamma rays.
TheAstrophysical Journal reports that the image obtained by astronomers is posted on the US National Astronomical Observatory's website.
Astronomers decided, after NASA's Fermi Space Telescope, which monitors space in the gamma ray range, detected high-energy rays emitted from the galaxy TXS 0128 + 554, which is located 500 million light years from Earth, to study this site in detail, using the system VLBA radio telescopes made of 10 telescopes are scattered in different regions of the United States.
The composite multi-frequency image taken by the VLBA system consists of six images taken at a frequency of 2.2 to 22.2 GHz. And high frequency images are more accurate and clear.
TXS 0128 + 554 galaxy activity began about 80 years ago. According to the researchers, the gap between the petals and the central region indicates that the emission of gamma rays was not continuous, stopped at some point, and resumed about 10 years ago.
"This is one of the smallest" jet engines "in systems that emit gamma rays," says Matthew Lister, head of the research team from Purdue University.
The diameter of the radiating areas is about 35 light years. These regions are located in the center of the galaxy, where the black hole is a million times the mass of the sun.
