A Semi-analytic Ray-tracing Algorithm for Weak Lensing
Baojiu Li, Lindsay J. King, Gong-Bo Zhao +1
We propose a new ray-tracing algorithm to measure the weak lensing shear and convergence fields directly from N-body simulations. We calculate the deflection of the light rays lens…
Mass of Galactic Lenses in Modified Newtonian Dynamics
Mu-Chen Chiu, Chung-Ming Ko, Yong Tian +1
Using strong lensing data Milgrom's MOdified Newtonian Dynamics (MOND) or its covariant TeVeS (Tensor-Vector-Scalar Theory) is being examined here as an alternative to the conventi…
Modified Kepler's Law, Escape Speed and Two-body Problem in MOND-like Theories
Hongsheng Zhao, Baojiu Li, Olivier Bienaymé
We derive a simple analytical expression for the two-body force in a sub-class of MOND-like theories and make testable predictions in the modification to the two-body orbital perio…
Substructure lensing in galaxy clusters as a constraint on low-mass sterile neutrinos in tensor-vector-scalar theory: The straight arc of Abell 2390
Martin Feix, HongSheng Zhao, Cosimo Fedeli +2
Certain covariant theories of the modified Newtonian dynamics paradigm seem to require an additional hot dark matter (HDM) component - in the form of either heavy ordinary neutrino…
Mass discrepancy in galaxy clusters as a result of the offset between dark matter and baryon distributions
HuanYuan Shan, Bo Qin, HongSheng Zhao
Recent studies of lensing clusters reveal that it might be fairly common for a galaxy cluster that the X-ray center has an obvious offset from its gravitational center which is mea…
Lopsidedness of cluster galaxies in modified gravity
Xufen Wu, HongSheng Zhao, Benoit Famaey
We point out an interesting theoretical prediction for elliptical galaxies residing inside galaxy clusters in the framework of modified Newtonian dynamics (MOND), that could be use…
Offset between dark matter and ordinary matter: evidence from a sample of 38 lensing clusters of galaxies
HuanYuan Shan, Bo Qin, Bernard Fort +3
We compile a sample of 38 galaxy clusters which have both X-ray and strong lensing observations, and study for each cluster the projected offset between the dominant component of b…
Comparing different realizations of modified Newtonian dynamics: virial theorem and elliptical shells
HongSheng Zhao, Benoit Famaey
There exists several modified gravity theories designed to reproduce the empirical Milgrom's formula (MOND). Here we derive analytical results in the context of the static weak-fie…
Structure Formation by the Fifth Force III: Segregation of Baryons and Dark Matter
Baojiu Li, Hongsheng Zhao
In this paper we present the results of -body simulations with a scalar field coupled differently to cold dark matter (CDM) and baryons. The scalar field potential and coupling…
