We develop a new method to predict the density associated with weak-lensing maps of (un)relaxed clusters in a range of theories interpolating between general relativity (GR) and modified Newtonian dynamics (MOND). We apply it to fit the lensing map of the Bullet merging cluster 1E 0657-56, in order to constrain more robustly the nature and amount of collisionless matter in clusters beyond the usual assumption of spherical equilibrium (Pointecouteau & Silk) and the validity of GR on cluster… Expand

MOND plus classical neutrinos are not enough for cluster lensing
Clusters of galaxies offer a robust test bed for probing the nature of dark matter that is insensitive to the assumption of the gravity theories. Both Modified Newtonian Dynamics (MOND) and GeneralExpand

The observation that, although modified gravity may indeed manage to replace dark matter, it is likely to do so by becoming or at least incorporating a dark matter theory itself is concluded. Expand
Neutrinos as cluster dark matter
The dynamical mass of clusters of galaxies, calculated in terms of MOdified Newtonian Dynamics (MOND), is a factor of 2 or 3 times smaller than the Newtonian dynamical mass but remains significantlyExpand
Modified Newtonian Dynamics (MOND): Observational Phenomenology and Relativistic Extensions
It is shown that many of these puzzling observations are predicted by one single relation — Milgrom’s law — involving an acceleration constant a0 on the order of the square-root of the cosmological constant in natural units. Expand

Does the Cosmological Expansion Change Local Dynamics?
This work analyzes whether this coincidence between the closeness of the acceleration scale and the Hubble constant cH0≈10−9 h m/s2 might have a Cosmological origin for scalar-Tensor and spinor-tensor theories by performing detailed calculations for perturbations that represent the local matter distribution on the top of the cosmological background.

The relation between stellar mass and weak lensing signal around galaxies: implications for modified Newtonian dynamics
We study the amplitude of the weak gravitational lensing signal as a function of stellar mass around a sample of relatively isolated galaxies. This selection of lenses simplifies the interpretationExpand
