Abstract: Abstract In a centrifuged model, the centrifugal acceleration increases radially outward from the axis of rotation. The variations in the magnitude and direction of the centrifugal acceleration will inevitably result in a distortion of the… read more here.

DOI: 10.1088/1367-2630/aaca23
Abstract: Recently a remarkable relation has been demonstrated between the observed radial acceleration in disk galaxies and the acceleration predicted on the basis of baryonic matter alone. Here we study this relation within the framework of… read more here.

DOI: 10.1093/mnras/stz1272
Abstract: Recent observations of rotationally supported galaxies show a tight correlation between the observed radial acceleration at every radius and the Newtonian acceleration generated by the baryonic mass distribution, the so-called radial acceleration relation (RAR). The… read more here.

DOI: 10.1103/physrevd.102.024068
Abstract: Recent observations of anomalous line-of-sight velocity dispersions of two ultra-diffuse galaxies (UDGs) provide a stringent test for modified gravity theories. While NGC 1052-DF2 exhibits an extremely low dispersion value ($\sigma \sim 7.8_{-2.2}^{+5.6}$ km/s), the reported… read more here.

Radial acceleration relation from symmetron fifth forces

DOI: 10.1103/physrevd.95.064050
Abstract: We show that the radial acceleration relation for rotationally supported galaxies may be explained, in the absence of cold dark matter, by a nonminimally coupled scalar field, whose fifth forces are partially screened on galactic… read more here.
