System radio surveys in the Ursa Major region show that the active nuclei of many different types of galaxies may be Assets come in different ways.
Some people are very greedy, They will consume as much material as possible; Other studies have revealed some new research results, some are digested more slowly, while others are about to starve to death.Astronomy and AstrophysicsBy British and Dutch scientists.
The study also showed that the accretionary phase sometimes coincides with the star formation phase, and sometimes it does not. If stars are forming, The activity in the nucleus is difficult to detect.
Third, the nuclear proliferation process can Produce or not produce jetNo matter how fast the black hole ingests food.
According to lead researcher Jack Radcliffe (Jack Radcliffe), the observations also show that: Radio telescopes are the most useful Study the eating habits of black holes in the distant universe. “This is good news because the SKA radio telescope is about to appear, which will allow us to understand the universe more deeply.”
Peter Barthel, a co-author of the University of Groningen in the Netherlands, added in the statement: “We are increasingly showing that all galaxies have Huge black hole In their center. Of course, these must have developed to the current level. It seems that due to our observations, we have now seen these growth processes and are slowly but surely beginning to understand them. “
The new observations add data from sensitive radio telescope networks, including the UK’s national e-MERLIN facility and the European VLBI network (EVN).
