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…
Dark matter halo occupation: environment and clustering
Rupert Croft, Tiziana Di Matteo, Nishikanta Khandai +3
We use a large dark matter simulation of a LambdaCDM model to investigate the clustering and environmental dependence of the number of substructures in a halo. Focusing on redshift…
Terapixel imaging of cosmological simulations
Yu Feng, Rupert A. C. Croft, Tiziana Di Matteo +8
The increasing size of cosmological simulations has led to the need for new visualization techniques. We focus on Smoothed Particle Hydrodynamical (SPH) simulations run with the GA…
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…
