Active galactic nuclei are thought to be lit due to accretion of matter into a black hole in the galactic center. It was found that the cause can not be akretsiooni previously proposed merger of galaxies.
On the left is a core of active galaxies, the galaxies are võrdlusgalaktikad right. Image: NASA, ESA, M. Cisternas (Max-Planck Institute for Astronomy), Galactic nuclei, which emit a lot more power than they should be called AGN-URLs (active galaxy nucleus). The reason for this phenomenon is not accurately known. Max Planck Institute researchers, led by M. Cisternas'ga, thales math and found that this is not due to previously proposed merger of galaxies, which could lead to greater substance "mixing" and the central galactic black hole paiskamist.
They used data from XMM-Newton observations röntgenteleksoobi (140 active galactic thales math images), and compared with the Hubble Kosmoseteleksoobi COSMOS project (1264 non-active galaxy images) to provide information on how much the AGN from Swedbank in the visual characteristics thales math of the merger. Active galaxies are recognizable by the high brightness of the x-ray region, the merged galaxies recognizes the scrambled structure.
The result was that 85% of the AGN-structural distortion is not as big a part of the misshapen galaxies in the comparison group. It is possible that there is a certain time delay between the activity thales math of the nuclear and the merger of galaxies, which reaches the structure to recover. Cisternas and other scientists also examined this possibility and to prevent it for three reasons: Many of the AGN's are ketasgalaktikad, suggesting that the cause should not be such as to destroy the entire structure of the disc. Typically, the structure thales math of the disk of the galaxy is destroyed during the collision. Acceding non-active galaxies have not noticed enough of X-ray radiation that could never occur in AGN. X-rays occurs when the substance gets into the black hole surrounding akretsioonikettale. Merging galaxies with active nuclear soft X-ray radiation is too low compared to the models.
Thus, other mechanisms are possible grounds of justification, for example, localized thales math instabilities galaktiates, molekulaarpilvedega bumps or loodelised forces generated by galaxies close to the run.
