Stacy McGaugh

Professor and Chair of Astronomy

Stacy McGaugh

Professor Stacy McGaugh studies galaxies, cosmology, and the mass discrepancy problem. His primary interest is in low surface brightness galaxies. These diffuse objects tell us a great deal about galaxy formation and evolution. He has worked extensively on galaxy dynamics, showing that the Tully-Fisher relation is fundamentally a relation between the rotation speed of a spiral galaxy and its baryonic mass (the sum of stars and gas). He successfully predicted the velocity dispersions of many of the dwarf satellite galaxies of Andromeda as they were discovered. His contributions to cosmology include the quantitatively accurate prediction of the amplitude ratio of the first-to-second peak of the acoustic power spectrum of the cosmic microwave background.

Professor McGaugh was a student at MIT, Princeton, and the University of Michigan. He held research fellowships at the Institute of Astronomy of the University of Cambridge, the Department of Terrestrial Magnetism of the Carnegie Institution of Washington, and Rutgers University. Prior to joining the faculty at Case Western Reserve, McGaugh was a professor in the Astronomy department at the University of Maryland, College Park.
