Predictions of Quasar Clustering: Redshift, Luminosity and Selection Dependence
Robert J. Thacker, Evan Scannapieco, H. M. P. Couchman +1
We show that current clustering observations of quasars and luminous AGN can be explained by a merger model augmented by feedback from outflows. Using numerical simulations large e…
Subhaloes in Scale-Free Cosmologies
P. J. Elahi, R. J. Thacker, L. M. Widrow +1
We explore the dependence of the subhalo mass function on the spectral index n of the linear matter power spectrum using scale-free Einstein-de Sitter simulations with n=-1 and n=-…
An N-body/SPH Study of Isolated Galaxy Mass Density Profiles
Kelly Foyle, Stephane Courteau, Robert Thacker
We investigate the evolution of mass density profiles in secular disk galaxy models, paying special attention to the development of a two-component profile from a single initial ex…
