Overview: Milky Way Evolution, velocity fields in barred galaxies, structure formation in barred galaxies. Age indicators of structure in galaxies. Mock stellar catalogs. Dark matter halo dynamics
Bars are the most ubiquitous
non-axisymmetric structure observed in the local
universe, observed in
roughly two-thirds of local galaxies. My work focuses on
numerical simulations and analytic calculations to examine
processes related to the formation and evolution of
One result to come of this work is the discovery of a trapped component in the dark matter halo that mimics the stellar bar, which we refer to as the shadow bar. Click on the image below for a more comprehensive look at the shadow bar work, or read the MNRAS paper.
The shadow bar has
consequences for the

The combination of the stellar and shadow bar drives non-axisymmetric structure in the dark matter halo--which has consequences for direct detection experiments on Earth.
