Extracting information from the exteriors of dark matter halos
While significant amounts of time has been spent studying dark matter halos, the environment around halos and the impact this environment has on structures that pass through it has not been investigated in nearly as much detail. In this thesis we perform several different studies all related to …

GALAXY-HALO CONNECTION AND CLUSTERING IN THE PRESENCE OF DYNAMICAL DARK ENERGY AND MASSIVE NEUTRINOS
… has applied to these simulations the subhalo abundance matching (SHAM) technique, which assumes a one-to-one relation between a physical property of a dark matter halo/subhalo and an observational property of the galaxy that it hosts. The author has adopted an empirical parameterisation of the …

Probing local group galactic substructure with cosmological simulations
… cusp/core problems, which concern the expected abundance of satellites and their inner structure. This Ph.D. thesis consists of a series of studies using dark matter only cosmological N-body simulations of MW-mass galaxies to address topics related to these issues. In light of the recent Planck …

Studying the Building Blocks of the Universe: the faint, low-mass galaxies
… We compute a volume-averaged UV-to-Ha ratio by abundance matching the rest-UV and Ha luminosity functions and find the observed ratio to deviate from the expectation for constant star-formation history for low-mass galaxies. We conclude that this could be due to a larger contribution from …
