Markarian 817's Black Hole Influences Galaxy Evolution with Ultra-Fast Winds

A recent study reveals that the black hole in galaxy Markarian 817 has generated ultra-fast winds, significantly impacting star formation and the structure of its host galaxy.

  • ESA's XMM-Newton telescope detects ultra-fast winds from the black hole in Markarian 817, altering the galaxy's structure.
  • The winds, lasting about a year, prevented new stars from forming by clearing out interstellar gas.
  • This phenomenon was observed in a galaxy not at its Eddington Limit, suggesting black holes can reshape galaxies more than previously thought.
  • The discovery challenges the understanding of black hole and galaxy co-evolution, showing even 'snacking' black holes can have significant impacts.
  • Multiple telescopes, including NASA's Swift and NuSTAR, contributed to uncovering the obscured X-ray signals from the black hole.
