A gravitational anomaly is found at weak gravitational acceleration g N≲ 10− 9 ms− 2 from
analyses of the dynamics of wide binary stars selected from the Gaia DR3 database that …

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 …

(Abridged) Fundamental tensions between observations and dark-matter based
cosmological models have emerged. This updated review has two purposes: to explore new …

We present the first hydrodynamical cosmological simulations in the νHDM framework
based on Milgromian dynamics (MOND) with light (11 eV) sterile neutrinos. νHDM can …

Tidal streams of disrupted clusters are powerful probes of the gravitational potential of the
Galaxy and they are routinely detected in the stellar halo of the Milky Way. It was recently …

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 …

Star clusters are among the first celestial objects catalogued by early astronomers. As
simple and coeval populations, their study has been instrumental in charting the properties …

Modified Newtonian dynamics (MOND), postulating a breakdown of Newtonian mechanics
at low accelerations, has considerable success at explaining galaxy kinematics. However …

The observed radial accelerations of 462 early-type galaxies (ETGs) at their half-mass radii
are discussed. They are compared to the baryonic masses of the same galaxies, which are …

MOND is an alternative paradigm of dynamics, seeking to replace Newtonian dynamics and
general relativity. It aims to account for the ubiquitous mass discrepancies in the Universe …
