Strong clustering of underdense regions and the environmental dependence of clustering from Gaussian initial conditions
Ummi Abbas, Ravi K. Sheth
We discuss two slightly counter-intuitive findings about the environmental dependence of clustering in the Sloan Digital Sky Survey. First, we find that the relation between cluste…
The environmental dependence of galaxy clustering in the Sloan Digital Sky Survey
Ummi Abbas, Ravi K. Sheth
A generic prediction of hierarchical clustering models is that the mass function of dark haloes in dense regions in the Universe should be top-heavy. We provide a novel test of thi…
The environmental dependence of clustering in hierarchical models
Ummi Abbas, Ravi K. Sheth
In hierarchical models, density fluctuations on different scales are correlated. This induces correlations between dark halo masses, their formation histories, and their larger-sca…
How does clustering depend on environment?
Ummi Abbas, Ravi K. Sheth
According to the current paradigm, galaxies form and reside in extended cold dark matter (CDM) halos and in turn are key tracers of cosmological structure. Understanding how differ…
