Intermediate-richness galaxy groups are an important test ground for MOND. First, they constitute a distinct type of galactic systems, with their own evolution histories and underlying physical processes; secondly, they probe little-chartered regions of parameter space, as they have baryonic masses similar to massive galaxies, and similar velocity dispersions, but much larger sizes -- similar to cluster cores (or even to clusters), but much lower dispersions. Importantly in the context of MOND… 
Predicted MOND velocity dispersions for a catalog of ultra-diffuse galaxies in group environments
The possibility that ultra-diffuse galaxies are lacking dark matter has recently stimulated interest to check the validity of modified Newton dynamics (MOND) predictions on the scale of such
On the generalized Faber-Jackson relation for galaxy clusters
The significant deviations among observations and the expectations based on self-similar scaling model of galaxy clusters, especially up to redshift $z\lesssim 0.4$, constrain the evolution of the
Scale-invariant dynamics of galaxies, MOND, dark matter, and the dwarf spheroidals
The Scale-Invariant Vacuum (SIV) theory is based on Weyl's Integrable Geometry, endowed with a gauge scalar field. The main difference between MOND and the SIV theory is that the first considers a
Are Disks of Satellites Comprised of Tidal Dwarf Galaxies?
It was found that satellites of nearby galaxies can form flattened co-rotating structures called disks of satellites or planes of satellites. Their existence is not expected by the current galaxy

Recently, from the new Spitzer Photometry and Accurate Rotation Curves data, McGaugh, Lelli & Schombert reported a tight radial acceleration relation between the observed total acceleration and the
Astromechanics of Dual Universe: A New Possible Explanation for the Universe Unsolved Problems
The necessity of the dark energy and dark matter in the present universe could be a consequence of the antimatter elimination assumption in the early universe. Current cosmological models that rely
Early Universe Plasma Separation and the Creation of a Dual Universe
The Planck Legacy recent release revealed a closed and positively curved early universe with a confidence level greater than 99%. In this study, the Friedmann–Lemaîtree–Robertson–Walker (FLRW) metric
The Scale-Invariant Vacuum (SIV) Theory: A Possible Origin of Dark Matter and Dark Energy
The Scale Invariant Vacuum (SIV) theory rests on the basic hypothesis that the macroscopic empty space is scale invariant. This hypothesis is applied in the context of the Integrable Weyl Geometry,
Thin Shells in General Relativity Without Junction Conditions: a Model for Galactic Rotation and the Discrete Sampling of Fields
Interest in general relativistic treatments of thin matter shells has flourished over recent decades, most notably in connection with astrophysical and cosmological applications such as black hole


MOND in galaxy groups
Galaxy groups, which have hardly been looked at in MOND, afford probing the acceleration discrepancies in regions of system-parameter space that are not accessible in well-studied galactic systems,
Galaxy groups and clouds in the local (z∼ 0.01) Universe
We present an all-sky catalogue of 395 nearby galaxy groups revealed in the Local Supercluster and its surroundings. The groups and their associations are identified among 10 914 galaxies at |b| >
X-ray group and cluster mass profiles in MOND: unexplained mass on the group scale
Although very successful in explaining the observed conspiracy between the baryonic distribution and the gravitational field in spiral galaxies without resorting to dark matter (DM), the modified
The dynamics of isolated Local Group galaxies
We measured velocities of 862 individual red giant stars in seven isolated dwarf galaxies in the Local Group: NGC 6822, IC 1613, VV 124 (UGC 4879), the Pegasus dwarf irregular galaxy (DDO 216), Leo
Nearby groups of galaxies in the Hercules–Bootes constellations
We consider a sample of 412 galaxies with radial velocities VLG < 2500 kms−1 situated in the sky region of RA = 13.m 0–19.m 0, Dec = +10◦...+40◦ between the Local Void and the Supergalactic plane.
Modified Newtonian Dynamics Mass-to-Light Ratios for Galaxy Groups
I estimate modified Newtonian dynamics (MOND) M/L-values for nine galaxy groups that were recently studied by Tully et al. Instead of the large M/L-values that they find with Newtonian dynamics (up
The dark halo of the Hydra I galaxy cluster: core, cusp, cosmological? Dynamics of NGC 3311 and its globular cluster system
Context. Some galaxy clusters exhibit shallow or even cored dark matter density profiles in their central regions rather than the predicted steep or cuspy profiles, conflicting with the standard
The Hydra I cluster core
Context. NGC 3311, the central galaxy of the Hydra I cluster, shows signatures of recent infall of satellite galaxies from the cluster environment. Previous work has shown that the line-of-sight
One Law To Rule Them All: The Radial Acceleration Relation of Galaxies
We study the link between baryons and dark matter in 240 galaxies with spatially resolved kinematic data. Our sample spans 9 dex in stellar mass and includes all morphological types. We consider (i)
