The James Webb Space Telescope was able to record a phenomenon that would have been impossible to observe with the help of ground-based instruments: it captured the merger of two ancient supermassive black holes, or, more precisely, detected their characteristic spectroscopic signals. One of the black holes located in the depths of two different galaxies has a mass of 50 million solar masses, and according to astronomers' assumptions, the other is also the same, only because of the dense gases surrounding the object, they could not determine its characteristics any less accurately. The recordings show the two black holes at a time when the universe was only about 740 million years old, and they and the galaxies were in the process of merging. Researchers have long sought to explain why it was possible for supermassive black holes to appear so early in the universe: one possible reason for this is the merger of massive black holes, which has now been confirmed by measurements from the James Webb Space Telescope. . “This discovery suggests that mergers are an important way for black holes to grow rapidly, even during cosmic dawn.” – He said to me Hannah Opler, lead author of the research study. After complete integration, researchers will be able to measure gravitational waves released by the “cosmic collision” with new-generation detectors, including one recently approved by the European Space Agency.
