A wealth of astronomical data indicate the presence of mass discrepancies in the Universe.
The motions observed in a variety of classes of extragalactic systems exceed what can be …

MOND is a paradigm that contends to account for the mass discrepancies in the Universe
without invoking 'dark'components, such as 'dark matter'and 'dark energy'. It does so by …

We propose a relativistic gravitational theory leading to modified Newtonian dynamics, a
paradigm that explains the observed universal galactic acceleration scale and related …

We study the link between baryons and dark matter (DM) in 240 galaxies with spatially
resolved kinematic data. Our sample spans 9 dex in stellar mass and includes all …

We propose a novel theory of dark matter (DM) superfluidity that matches the successes of
the Λ cold dark matter (Λ CDM) model on cosmological scales while simultaneously …

Galaxies follow a tight radial acceleration relation (RAR): the acceleration observed at every
radius correlates with that expected from the distribution of baryons. We use the Markov …

The current standard model of cosmology (SMoC) requires The Dual Dwarf Galaxy Theorem
to be true according to which two types of dwarf galaxies must exist: primordial dark-matter …

The concordance model of cosmology, ΛCDM, provides a satisfactory description of the
evolution of the universe and the growth of large-scale structure. Despite considerable effort …

A general account of modified Newtonian dynamics (MOND) theory is given. I start with the
basic tenets of MOND, which posit departure from standard dynamics in the limit of low …

Predictions of the concordance cosmological model (CCM) of the structures in the
environment of large spiral galaxies are compared with observed properties of Local Group …
