(2015-07-20)Department: PhysicsIn this dissertation I present several different but related analyses of structure on both Galactic and extragalactic scales. I first investigate whether measurements of the moments of large-scale structure can yield ...

(Vanderbilt University. Dept. of Physics and Astronomy, 2012-04)Cosmic microwave background (CMB) observations suggest the possibility of an extra dark radiation component, while the current evidence from big bang nucleosynthesis (BBN) is more ambiguous. Dark radiation from a decaying ...

(2019-03-28)Department: PhysicsA covariant description of quantum matter fields in the early universe underpins models for the origin of species, e.g. baryogenesis and dark matter production. In nearly all cases the relevant cosmological observables are ...

(Vanderbilt University. Dept. of Physics and Astronomy, 2008-04-20)We use projected number density profiles of galaxy groups to investigate the relationship between galaxy group structure and dark matter structure within halos. We primarily study a specific model of how galaxies populate ...

(2019-07-18)Department: PhysicsThe Universe is comprised of structures on all scales, ranging from stars and planets to galaxies and clusters. These structures form part of a much bigger web-like structure built with systems of galaxies, filaments, ...
