Observed and simulated evolution of the B-band luminosity function of quasars between

The simulated luminosity function is for black holes accreting at a rate of

where vc is the halo circular velocity and 
Notice that in this model the real growth time is 
since winds become so powerful that the inflow is turned into an outflow before a time taccr has elapsed. This figure has been plotted for
