The effect of supermassive black holes in the galactic nuclei extends far beyond the limits of parental galaxies and can even affect the neighboring galaxies. The unexpected effect of the giant objects found astrophysics of the Institute of Astronomy of the Max Planck Society, as well as their colleagues from Mexico and the United States, whose article was published in the Nature magazine.
Processes in dwarf-satellite galaxies depend on the medium surrounding the central galaxy. It is believed that this environment, in turn, is experiencing an influence on the part of the supermassive black hole, despite the distance in tens of thousands of light years between them. However, the nature of this connection remained for astronomers an uninterrupted due to scarce observation data.
In the new scientific work, scientists took advantage of the catalog of the Sloan digital celestial review and identified 124 163 satellite galaxies, determining their position relative to the large and small axes of the central galaxy (most of the central galaxies in the study had the form of an ellipse). It turned out that the extinct dwarf galaxies in which there are no star formation is relatively rarely found along the small axes, which seems illogical, given that supermassive black holes in the central kernel emit mass and energy mainly in the direction of the small axis of the galaxy (this should be “blowing” Suitable for the formation of stars matter) due to the relatively low resistance of the interstellar environment.
How scientists write, it can be explained by several reasons. The galaxies could initially be formed in other conditions that are not related to the current state of the nearby environment. However, the role was also played by the interaction between the satellite galaxy and the Galo Central Galaxy.
To check both scenarios, scientists took advantage of the model of the virtual Universe Illustristng, which differs from previous models of improved simulation of active galactic nuclei (in which a nursing supermassive black hole is located). It turned out that an anomaly in the distribution of galaxic satellites arises precisely because of the influence of the kernel, which acts far beyond the central galaxy.
Energy emissions from black holes are created in the near-density area of the region, which reduces the effectiveness of the processes responsible for the “quenching” of dwarf galaxies. These include, for example, the “effect of tidal robbery” (eng. Ram Pressure Stripping). However, the authors of the article emphasize that they cannot exclude another scenario, according to which the expiring substance of their galaxy kernel is more intensifying star formation, and not just stops its quenching.
