Measuring Mass of Gas in Central Galaxies using weak lensing and satellite kinematics in MOND
Li Ma, Ziwen Zhang, Huiyuan Wang +1
In Milgrom's modified Newtonian dynamics (MOND) framework, the dynamical mass of a galaxy is fully determined by its baryonic matter distribution. We fit the distribution of cold a…
