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 galaxies. Five new, most probably irreconcilable problems are uncovered: 1) A wide variety of published CCM models consistently predict some form of relation between dark-matter-mass and luminosity for the Milky Way (MW) satellite galaxies, but none is observed. 2) The mass function of luminous sub-haloes predicted by the CCM… Expand

Lessons from the Local Group (and beyond) on dark matter
The existence of exotic dark matter particles outside the standard model of particle physics constitutes a central hypothesis of the current standard model of cosmology (SMoC). Using a wide range ofExpand
The Number of Dwarf Satellites of Disk Galaxies versus their Bulge Mass in the Standard Model of Cosmology
There is a correlation between bulge mass of the three main galaxies of the Local Group (LG), i.e. M31, Milky Way (MW), and M33, and the number of their dwarf spheroidal galaxies. A similarExpand
The observed spatial distribution of matter on scales ranging from 100kpc to 1Gpc is inconsistent with the standard dark-matter-based cosmological models
The spatial arrangement of galaxies (of satellites on a scale of 100kpc) as well as their three-dimensional distribution in galaxy groups such as the Local Group (on a scale of 1Mpc), theExpand
A correlation between the number of satellites and the bulge-to-total baryonic mass ratio extending beyond the Local Group
Recent observations of the fields surrounding a few Milky-Way-like galaxies in the local Universe have become deep enough to enable investigations of the predictions of the standard LCDM cosmologicalExpand
Galactic rotation curves, the baryon-to-dark-halo-mass relation and space–time scale invariance
Low-acceleration space-time scale invariant dynamics (SID, Milgrom 2009a) predicts two fundamental correlations known from observational galactic dynamics: the baryonic Tully-Fisher relation (BTFR)Expand
The number of tidal dwarf satellite galaxies in dependence of bulge index
We show that a significant correlation (up to 5sigma) emerges between the bulge index, defined to be larger for larger bulge/disk ratio, in spiral galaxies with similar luminosities in the Galaxy ZooExpand
Galaxies as simple dynamical systems: observational data disfavor dark matter and stochastic star formation
According to modern theory, galactic evolution is driven by the dynamics of dark matter and stochastic star formation, but galaxies are observed to be simple systems. The existence of dark matterExpand
Rotation curves of galaxies and the stellar mass-to-light ratio
Mass models of a sample of 171 low- and high-surface brightness galaxies are presented in the context of the cold dark matter (CDM) theory using the NFW dark matter halo density distribution toExpand
Dwarf spheroidal satellites of the Milky Way from dark matter free tidal dwarf galaxy progenitors: maps of orbits
The long term time evolution of tidal dwarf satellite galaxies with two different initial densities orbiting a host galaxy that resembles the Milky Way has been studied using a large set of NewtonianExpand
The failures of the standard model of cosmology require a new paradigm
Cosmological models that invoke warm or cold dark matter cannot explain observed regularities in the properties of dwarf galaxies, their highly anisotropic spatial distributions, nor the correlationExpand


Central Mass and Luminosity of Milky Way Satellites in the Λ Cold Dark Matter Model
It has been pointed out that the Galactic satellites all have a common mass around 107 M ☉ within 300 pc (M 0.3), while they span almost four orders of magnitude in luminosity. It is argued that thisExpand
How cold is dark matter? Constraints from Milky Way satellites
We test the luminosity function of Milky Way satellites as a constraint for the nature of dark matter particles. We perform dissipationless high-resolution N-body simulations of the evolution ofExpand
The dwarf satellite galaxies in the Local Group are generally considered to be hosted in dark matter subhalos that survived the disruptive processes during infall onto their host halos. It hasExpand
The Observed Properties of Dark Matter on Small Spatial Scales
A synthesis of recent photometric and kinematic data for several of the most dark matter dominated galaxies, the dwarf spheroidal Galactic satellites, and compare them to star clusters provides new information about the nature of the dominant form of dark matter. Expand

Dwarf Cosmology with the Stromlo Missing Satellites Survey
The standard Lambda Cold Dark Matter model is considered to be a triumph of theoretical astrophysics but observations of the Milky Way and its system of satellite galaxies irresistibly signal thatExpand
Clumps and streams in the local dark matter distribution
A simulation that resolves dark matter substructure even in the very inner regions of the Galactic halo is reported, finding hundreds of very concentrated dark matter clumps surviving near the solar circle, as well as numerous cold streams. Expand
A common mass scale for satellite galaxies of the Milky Way
New measurements of the velocities of the stars in these galaxies are used to show that they are consistent with them having a common mass of about 107 within their central 300 parsecs, demonstrating that the faintest of the Milky Way satellites are the most dark-matter-dominated galaxies known.
