AbstractUsing strong lensing data, Milgrom's modified Newtonian dynamics (MOND) and its covariant TeVeS (tensor-vector-scalar theory) are examined here as an alternative to the conventional ΛCDM paradigm. We examine 10 double-image, gravitational lensing systems in which the lens masses have been estimated by stellar population synthesis models. While mild deviations exist, we find no strong case of outliers to the TeVeS theory. © 2011 American Physical Society.
