What to know

  • Black hole winds carry 100 times more energy than previously thought, extending 300,000 light-years beyond host galaxies.
  • Energy in the turbulence rivals several billion supernova explosions, establishing black holes as major cosmic energy transporters.
  • XRISM satellite's high-precision X-ray measurements of quasar H1821+643 revealed this previously underestimated influence on galactic environments.

    Study published showing black hole winds rival energy of several billion supernovas

    Science Daily releases full findings showing the energy in black hole-driven turbulence is comparable to the output of several billion supernova explosions, demonstrating black holes' role as key drivers of gas flows and cosmic energy distribution across vast regions of space.

    “For the first time, we have shown that black holes influence the broader cosmic environment through a shock wave of astonishing power. Black holes are key drivers of gas flows and motion in space, transporting vast amounts of energy to different regions of the cosmos.”

    XRISM observations reveal black hole winds 100 times more powerful than previously thought — Researchers led by Satoshi Yamada at Tohoku University used the XRISM X-ray satellite to study quasar H1821+643 and found that supermassive black hole winds carry energy across roughly 300,000 light-years, extending far beyond the host galaxy. The energy contained in the turbulence was approximately 100 times greater than earlier estimates.
