Growth and anisotropy of ionization fronts near high redshift quasars in the MassiveBlack simulation
Yu Feng, Rupert A. C. Croft, Tiziana Di Matteo +1
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 a…

Growth of Early Supermassive Black Holes and the High-Redshift Eddington Ratio Distribution
Colin DeGraf, Tiziana Di Matteo, Nishikanta Khandai +1
Using a new large-scale (~ 0.75 Gpc)^3 hydrodynamic cosmological simulation we investigate the growth rate of supermassive black holes in the early universe (z > 4.75). Remarkably,…
