| Abstract: |
We model the formation, evolution, and multi-band properties of quasars at z ∼ 6, by combining hydrodynamic simulations (Li et al. 2007) with radiative transfer calculations using ART2 – All-wavelength Radiative Transfer with Adaptive Refinement Tree (Li et al. 2008). Our model shows that luminous quasars at z ∼ 6 can form through hierarchical galaxy mergers in the LCDM cosmology, and our calculations reproduce a number of observations of z ∼ 6 quasars, including the black hole masses, dust properties, and multi-wavelength SEDs and luminosities. We find that SMBHs grow via gas accretion under Eddington limit, without invoking exotic process. The quasar host obeys the Magorrian relation observed locally as a result of coeval growth of the SMBH and its host galaxy. Furthermore, the quasar systems evolve from cold to warm ULIRGs as they transform from a starburst to a quasar. |
