Growth and anisotropy of ionization fronts near high-redshift quasars in the MassiveBlack simulation

Growth and anisotropy of ionization fronts near high-redshift quasars in the MassiveBlack simulation

We use radiative transfer to study the growth of ionized regions around the brightest, z = 8 quasars in a large cosmological hydrodynamic simulation that includes black hole growth and feedback (the MassiveBlack simulation). We find that in the presence of the quasars the comoving H ii bubble radii reach …
