Matthew Walker

Matthew Walker is a Professor in the Department of Physics at Carnegie Mellon University. His research focuses on astrophysics and cosmology, particularly the astrophysical properties of dark matter, with an emphasis on the study of dwarf galaxies surrounding the Milky Way and Andromeda. He uses optical imaging, spectroscopy, and dynamical modeling to investigate dark matter's behavior at small scales. Walker's work involves collaborations with major observatories such as the Magellan telescopes and the Very Large Telescope. His research bridges dynamics, cosmology, and particle physics, aiming to uncover the nature of dark matter through empirical observations.

Matthew G. Walker is a researcher focused on dark matter, galaxy formation, dwarf galaxies, and the Local Group. His work explores the dynamics and properties of dwarf spheroidal galaxies, including their velocity dispersion profiles and mass profiles. He investigates the role of dark matter in shaping galaxy structures and addresses challenges such as the core/cusp problem and the missing satellite problem. Walker's research also involves analyzing data from surveys like Gaia-ESO and the Magellan/MMFS survey to study stellar kinematics and dark matter interactions. His studies contribute to understanding the distribution and behavior of dark matter in the Milky Way's satellite systems.
