TeVeS/MOND is in harmony with gravitational redshifts in galaxy clusters

摘要: Wojtak, Hansen & Hjorth have recently claimed to confirm general relativity (GR) and rule out the tensor–vector–scalar (TeVeS) gravitational theory based on an analysis of redshifts galaxies in 7800 clusters. However, their ubiquitous modelling sources cluster fields with Navarro–Frenk–White mass profiles is neither empirically justified necessary radii clusters, nor germane case TeVeS. Using MONDian (where MOND stands for MOdified Newtonian Dynamics) isothermal sphere models consistently constructed within (equivalent TeVeS models), we can fit determined no worse than does GR dark haloes. Moreover, inappropriately used simple interpolating function μ scalar field TeVeS; consequent effective turns enhance potential, so contributes discrepancy which forms basis claims.
