1998ApJ...499...66M Testing the Hypothesis of Modified Dynamics with Low Surface Brightness Galaxies and Other Evidence STACY S. MCGAUGH Department of Terrestrial Magnetism, Carnegie Institution of Washington, 5241 Broad Branch Road NW, Washington, DC 20015 AND W. J. G. DE BLOK Kapteyn Astronomical Institute, Postbus 800, 9700 AV Groningen, The Netherlands Received 1997 September 5; accepted 1997 December 30 ABSTRACT The rotation curves of low surface brightness galaxies provide a unique data set with which to test alternative theories of gravitation over a large dynamic range in size, mass, surface density, and acceleration. Many clearly fail, including any in which the mass discrepancy appears at a particular length scale. One hypothesis, Modified Newtonian Dynamics (MOND), is consistent with the data. Indeed, it accurately predicts the observed behavior. We find no evidence on any scale that clearly contradicts MOND and much that supports it.
