# Modified Newtonian dynamics in the Milky Way

@article{Famaey2005ModifiedND, title={Modified Newtonian dynamics in the Milky Way}, author={Benoit Famaey and James Binney}, journal={Monthly Notices of the Royal Astronomical Society}, year={2005}, volume={363}, pages={603-608} }

Both microlensing surveys and radio-frequency observations of gas flow imply that the inner Milky Way is completely dominated by baryons, contrary to the predictions of standard cold dark matter (CDM) cosmology. We investigate the predictions of the modified Newtonian dynamics (MOND) formula for the Galaxy given the measured baryon distribution. Satisfactory fits to the observationally determined terminal-velocity curve are obtained for different choices of MOND’s interpolating function µ(x… Expand
