The Effect of Assembly Bias on Redshift Space Distortions
Nelson Padilla, Sergio Contreras, Idit Zehavi +2
We study potential systematic effects of assembly bias on cosmological parameter constraints from redshift space distortion measurements. We use a semi-analytic galaxy formation mo…
The Evolution of Assembly Bias
Sergio Contreras, Idit Zehavi, Nelson Padilla +3
We examine the evolution of assembly bias using a semi-analytical model of galaxy formation implemented in the Millennium-WMAP7 N-body simulation. We consider fixed number density…
The impact of assembly bias on the halo occupation in hydrodynamical simulations
M. Celeste Artale, Idit Zehavi, Sergio Contreras +1
We investigate the variations in galaxy occupancy of the dark matter haloes with the large-scale environment and halo formation time, using two state-of-the-art hydrodynamical cosm…
