Supermassive Black Holes Stifle Galaxy Growth

An artist’s rendition of the galaxies Akira (right) and Tetsuo (left) in action. Akira’s gravity pulls Tetsuo’s gas into its central supermassive black hole, fuelling winds that have the power to heat Akira’s gas. Because of the action of the black hole winds, Tetsuo’s donated gas is rendered inert, preventing a new cycle of star formation in Akira. Copyright : Prime Focus Spectrograph Project

Supermassive black hole winds in a newly discovered class of galaxies are so energetic they suppress future star formation. An international team involved in the SDSS-IV MaNGA (Sloan Digital Sky Survey-IV Mapping Nearby Galaxies at Apache Point Observatory) project is studying ~10,000 galaxies near Earth...
