Query: Substructure and the halo model of large-scale structure   We develop the formalism to include substructure in the halo model of
clustering. Real halos are not likely to be perfectly smooth, but have
substructure which has so far been neglected in the halo model -- our formalism
allows one to estimate the effects of this substructure on measures of
clustering. We derive expressions for the two-point correlation function, the
power-spectrum, the cross-correlation between galaxies and mass, as well as
higher order correlation functions. Simple forms of the formulae are obtained
for the limit in which the size of the subclumps and mass fraction in them is
small. Inclusion of substructure allows for a more accurate analysis of the
statistical effects of gravitational lensing. It can also bring the halo model
predictions into better agreement with the small-scale structure seen in recent
high resolution simulations of hierarchical clustering.
