Ultra-diffuse galaxies (UDGs) are attractive candidates to probe cosmological models and test theories of galaxy formation at low masses; however, they are difficult to detect because of their low surface brightness. In the Local Group a handful of UDGs have been found to date, most of which are satellites of the Milky Way and M31, and only two are

High-resolution galaxy spectra encode information about the stellar populations within galaxies. By investigating the properties of these stars, such as their ages, masses, and metallicities, we can gain insights into the underlying physical processes that drive the growth and transformation of galaxies over cosmic time, in particular, the triggers

We explore the interplay between Jeans analyses of velocity dispersions and millisecond-pulsar (MSP) timing measurements that trace line-of-sight accelerations to analyze the kinematics of Omega Centauri, performing the first combined analysis of its kind. By using HST proper motion data and recent MSP kinematic measurements, we are able to tightly
