Theoretical dark matter halo kinematics and triaxial shape
  In a recent paper, Salvador-Sol\'e et al. (2012) have derived the typical
inner structure of dark matter haloes from that of peaks in the initial random
Gaussian density field, determined by the power-spectrum of density
perturbations characterising the hierarchical cosmology under consideration. In
the present paper, we extend this formalism to the typical kinematics and
triaxial shape of haloes. Specifically, we establish the link between such halo
properties and the power-spectrum of density perturbations through the typical
shape of peaks. The trends of the predicted typical halo shape, pseudo
phase-space density and anisotropy profiles are in good agreement with the
results of numerical simulations. Our model sheds light on the origin of the
power-law-like pseudo phase-space density profile for virialised haloes.
