Fig. 9


Time evolution of the halo mass (in units of 1010M, green curve) and virial radius (in units of kpc; grey curve) as compared to the evolution of the BH mass (in units of 104M; red curve) during the QSO accretion history. By the time the SMBH has grown to 109M, the halo mass and virial radius have grown by a factor of ~ 150 and ~ 10, respectively.
