Accurate modeling of galaxy formation in a hierarchical, cold dark matter universe requires the use of sufficiently high-resolution merger trees to obtain convergence in the predicted properties of galaxies. When semi-analytic galaxy formation models... Read More about Achieving convergence in galaxy formation models by augmenting N-body merger trees.

Constraints on the identity of the dark matter from strong gravitational lenses (2016)
Journal Article

The cold dark matter (CDM) cosmological model unambiguously predicts that a large number of haloes should survive as subhaloes when they are accreted into a larger halo. The CDM model would be ruled out if such substructures were shown not to exist.... Read More about Constraints on the identity of the dark matter from strong gravitational lenses.
