  • Description:

    "Feedback from Active Black Holes: How a central black hole can control a galaxy"
    All large galaxies appear to have a central black hole with a mass about 0.1% that of the host galaxy. Evidence is growing that the black hole may be the prime mover here, despite the radius of the galaxy being a billion times larger than the radius of the black hole.

    The key is the enormous quantity of energy produced by matter falling onto the black hole. This can make the black hole active and cause energy to be fed back into the galaxy to push and heat its gas clouds.
