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 …

Stars that evaporate from their star cluster by the energy equipartition process end up in
either a leading or a trailing tidal tail. In Newtonian gravitation and for open star clusters in …

Context. Observational estimates of galaxy properties, including mass and star formation
rates (SFRs), rely on the inherent galaxy-wide initial mass function (gwIMF), which …

Simulations of structure formation in the standard cold dark matter cosmological model
quantify the dark matter halos of galaxies. Taking into account dynamical friction between …

Compact massive relic galaxies are a class of galaxies that exhibit characteristics
suggesting they have remained largely unchanged since their initial formation, making them …

Cosmological simulations predict that during the evolution of galaxies, the specific star
formation rate continuously decreases. In a previous study we showed that generally this is …

Aims. We explore the dynamical friction on a test mass in gravitational systems in the quasi-
linear formulation of modified Newtonian dynamics (QuMOND). Methods. Exploiting the …

We quantify the differences between stellar accelerations in disk galaxies formed in a
MONDian universe relative to galaxies with the identical baryonic matter distributions and a …
