Astronomical observations reveal a major deficiency in our understanding of physics—the
detectable mass is insufficient to explain the observed motions in a huge variety of systems …

We test Milgromian dynamics (MOND) using wide binary stars (WBs) with separations of 2–
30 kAU. Locally, the WB orbital velocity in MOND should exceed the Newtonian prediction …

General relativity and its Newtonian weak field limit are not sufficient to explain the observed
phenomenology in the Universe, from the formation of large-scale structures to the dynamics …

The existence of mutually correlated thin and rotating planes of satellite galaxies around
both the Milky Way (MW) and Andromeda (M31) calls for an explanation. Previous work in …

We conduct hydrodynamical MOND simulations of isolated disc galaxies over the stellar
mass range M⋆/M⊙= 107–1011 using the adaptive mesh refinement code phantom of …

The dynamical stability of disk galaxies is sensitive to whether their anomalous rotation
curves are caused by dark matter halos or Milgromian dynamics (MOND). We investigate …

Dark matter phenomena in rotationally supported galaxies exhibit a characteristic
acceleration scale of g†≈ 1.2× 10− 10 ms− 2. Whether this acceleration is a manifestation of …

When bars form within galaxy formation simulations in the standard cosmological context,
dynamical friction with dark matter (DM) causes them to rotate rather slowly. However …

Recently, the discovery of the radial acceleration relation (RAR) in galaxies has been
regarded as an indirect support of alternative theories of gravity such as modified Newtonian …

We carry out a test of the radial acceleration relation (RAR) for galaxy clusters from two
different catalogs compiled in literature, as an independent cross-check of two recent …
