Black holes are objects that are so tight that not even light can escape their gravitational train. Created from the spectacular death of massive stars or lurking as a super massive monster in galactic centers it was around you and created a border called Event Horizon – the point without return. Despite their name, which indicates emptiness, black holes are anything but the matter that is compressed into incredible densities while they violently transform their surroundings. They are surrounded by overheated accretion panes. Get powerful radiation rays over thousands of light years and distort the time itself, as predicted by Einstein's theory of relativity.

Super massive black holes and their guest galaxies have developed together despite their enormous differences in size and mass. It is believed that strong gas winds with extreme speeds from regions that surround black holes contain the key to understanding this connection. These high -speed outflows seem to be the growth of the black hole (by restricting how much matter falls) and the development of the galaxy (by pumping energy into the galaxy that can stop the star formation).
A team of researchers has found that the winds are not smooth as before, but as “bullets” of rapid-fire gas “with surprising amounts of energy”. This discovery, which changes our understanding of how galaxies develop with its central black holes, came from an international team that is led by the Japanese space agency (Jaxa). Professor Christine, who was carried out from the Center for Extra-Alactic astronomy, was one of two European scientists who were involved in this research as part of X-ray and spectroscopy mission (XRISM), the hot gas winds that flow through galaxies.

The team used the advanced spectroscopic instruments from Xrism and observed winds that flow from a super massive black hole at a slight speed of 20 to 30%. XRSIM is a common mission between the Japan Aerospace Exploration Agency, NASA and the ESA and is well suited for the task. Instead of a uniform river, they found that these winds contain at least five different gas components, which were moving at different speeds. The physical gas emissions occur in intermittent bursts such as geysers or through gaps in the surrounding room.
This knowledge determined the challenges of how galaxies and black holes develop together, especially since these winds transport more than 1,000 times more energy than previously known galactic winch. This groundbreaking observation, which is only possible with the unique ability of the XRISM to solve the complex speed structure of these cosmic drains, is fundamentally changing our understanding of the influence of black holes on their host galaxies.
