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

The dynamical study of nearby dwarf spheroidal galaxies has played a fundamental role in challenging the cold dark matter model. These studies, based on the analysis of resolved stellar populations, are limited by the fact that we can only probe a small population of the nearest nearby galaxies. In the coming years, ultra-deep surveys will increase

Cosmological hydrodynamical simulations, such as EAGLE and IllustrisTNG, provide valuable insights when coupled with high-quality survey data, enhancing our comprehension of galaxy evolution. In this work, we adopt a variance analysis of subsets of continuum-subtracted Sloan Digital Sky Survey (SDSS) spectra by Sharbaf+2023 and evaluate equivalent
