The Universal Rotation Curve of Disk Galaxies
In the standard model of cosmology, the formation and evolution of dark matter halos plays an essential role in galaxy development. However, the response of the halo to internal baryonic processes is difficult to observe. We tackle this problem through an investigation of the Universal Rotation …

The Universality of Intrinsic Flattening in Extragalactic Stellar Disks
Highly inclined (edge-on) galaxies provide the unique perspective necessary to constrain the intrinsic flattening, 𝑐/𝑎, of galactic disks. We use “dust-free” 3.6 𝜇m maps of 141 edge-on spiral galaxies from the Spitzer Survey of Stellar Structure in Galaxies (S4G) and its early-type galaxy extension …
