MOND rotation curves for spiral galaxies with Cepheid-based distances
Roelof Bottema, Jose L. G. Pestana, Barry Rothberg +1
Rotation curves for four spiral galaxies with recently determined Cepheid-based distances are reconsidered in terms of modified Newtonian dynamics (MOND). For two of the objects, N…
