The High-Speed Winds of Supermassive Black Holes.
The SUper massive Black hole Winds in the x-rAYS (SUBWAYS) project has presented the first results of its research into ultra-fast outflows (UFOs) emitted by supermassive black holes (SMBHs) at the center of active galactic nuclei (AGNs). The SUBWAYS team used the X-ray Multi-Mirror Mission (XMM) to analyze AGNs for more than 1.6 million seconds and found that in about 30% of the AGNs analyzed, there are space winds traveling at speeds of 10% to 30% of the speed of light. These winds are believed to play a vital role in shaping the evolution process of galaxies.
