What are the jets from a feeding blackhole made of?

  1. May 31, 2012 #1
    Hi all, The traditional image of a "feeding" blackhole has jets spewing from either pole of the axis of rotation. I know that these jets are accellerated to almost the speed of c, but I have been unable to determine if these jets are of mater / particles or energy. Could you tell me which (mater or energy) the jet are made of?

    Thanking you in anticipation.

    electromagnetic radiation, and therefore they do travel at the speed c, since visible light is a form of electromagnetic radiation

    Thanks FOIWATER. But why is it described as "accelerated" to the speed of light - doesn't that imply that at a point in time after leaving the blackhole it was travelling at less than c. And if so, how does EM radiation travel at less than c?

    Jets are made of highly ionized gas.

    One other thing is that jets are even more of a mystery than black holes.

    Thanks twofish.
