Mass in reletivistic jets

  1. Nov 5, 2013 #1
    I have done a little reading on relativistic jets coming out of black holes. No where could I find a hypothetical amount of mass getting launched out of the poles. I was looking for an "amount per second" estimate. I know that it probably differs depending on how large the BH is, I am just curious as to what the number could be.

    This paper derives some formulas from which the mass flow might be estimated:

    But they don't carry out any such calculations.

    This paper provides some numbers for the Lorentz factor (=50) and the total energy flow (10^46 ergs/sec):

    So if you assume that everything is an electron, then the total energy of each electron is gamma*mc^2, where the electron mass is 0.511 MeV/c^2 for each one, times 50 for the total energy.

    1 erg = 624,150 MeV/c^2 ... so now you can determine the total MeV flow per second, and divide by the amount per electron ... and you have electrons per second.
