The Formation of Galaxies Hosting z~6 Quasars
Nishikanta Khandai, Yu Feng, Colin DeGraf +2
We investigate the formation and properties of galaxies hosting z~6 quasars, in the gigaparsec scale cosmological hydrodynamical simulation: MassiveBlack, which includes a self-con…
Early Black Holes in Cosmological Simulations: Luminosity Functions and Clustering Behaviour
Colin DeGraf, Tiziana Di Matteo, Nishikanta Khandai +3
We examine predictions for the quasar luminosity functions (QLF) and quasar clustering at high redshift (z > 4.75) using MassiveBlack, our new hydrodynamic cosmological simulation…
Cold flows and the first quasars
Tiziana Di Matteo, Nishikanta Khandai, Colin DeGraf +4
Observations of the most distant bright quasars imply that billion solar mass supermassive black holes (SMBH) have to be assembled within the first eight hundred million years. Und…
The Halo Occupation Distribution of Active Galactic Nuclei
Suchetana Chatterjee, Colin DeGraf, Jonathan Richardson +3
Using a fully cosmological hydrodynamic simulation that self-consistently incorporates the growth and feedback of supermassive black holes and the physics of galaxy formation, we e…
The Halo Occupation Distribution of Black Holes: Dependence on Mass
Colin DeGraf, Matthew Oborski, Tiziana Di Matteo +4
We investigate the halo occupation distribution (HOD) of black holes within a hydrodynamic cosmological simulation that directly follows black hole growth. Similar to the HOD of ga…
