The dark matter in the galaxy cluster Abell 1689 is modelled as an isothermal sphere of neutrinos. New data on the $2d$ mass density allow an accurate description of its core and halo. The model has no "missing baryon problem" and beyond $2.1$ Mpc the baryons have the cosmic mass abundance. Combination of cluster data with the cosmic dark matter fraction -- here supposed to stem from the neutrinos -- leads to a solution of the dark matter riddle by left and right handed neutrinos with mass 1… Expand

The Standard Model of Particle Physics with Diracian Neutrino Sector
The minimally extended standard model of particle physics contains three right handed or sterile neutrinos, coupled to the active ones by a Dirac mass matrix and mutually by a Majorana mass matrix, which violates lepton number conservation and allows very feeble neutrinoless double beta decay.

Subjecting Dark Matter Candidates to the Cluster Test
Galaxy clusters, employed by Zwicky to demonstrate the existence of dark matter, pose new stringent tests. If merging clusters demonstrate that dark matter is self-interacting with cross sectionExpand
The Possibility of Particles Forming from a Bose-Einstein Condensate, in an Intense Magnetic or Gravitational Field
In the paper - based on a previous work regarding the cold particles forming process as collapsed cold clusters of gammons- considered as pairs: g * = (e - e + ) of axially coupled electrons withExpand
Modified Gravity and its test on galaxy clusters
The MOdified Gravity (MOG) theory of J. Moffat assumes a massive vector particle which causes a repulsive contribution to the tensor gravitation. For the galaxy cluster A1689 new data for the X-rayExpand
On a Plausible Triple Electro-gravito-informational Significance of the Fine Structure Constant
In the last century, a small minority of physicists considered a hypothetical binary logarithmic connection between the large and the small constants of physics, which also implies a base-2 power lawExpand
(Toy-model) A Simple “Digital” Vacuum Composed of Space Voxels with Quantized Energetic States
Based on a plausible electro-gravitational scaling factor of nature, this paper proposes a relatively simple “digital” vacuum toy model (DVTM) based on a quantized 3D space composed of space voxelsExpand


Neutrino dark matter in clusters of galaxies
We present a model calculation for the radial matter density and mass distribution in two clusters of galaxies (Coma and A119) including cold dark matter, massive though light (2 eV) neutrino darkExpand
Do non-relativistic neutrinos constitute the dark matter?
The dark matter of the Abell 1689 Galaxy Cluster is modeled by thermal, non-relativistic gravitating fermions and its galaxies and X-ray gas by isothermal distributions. A fit yields a mass ofExpand
The offsets between galaxies and their dark matter in Λ cold dark matter.
We use the ‘Evolution and Assembly of GaLaxies and their Environments’ (EAGLE) suite of hydrodynamical cosmological simulations to measure offsets between the centres of stellar and dark matterExpand
The behaviour of dark matter associated with four bright cluster galaxies in the 10 kpc core of Abell 3827
Galaxy cluster Abell 3827 hosts the stellar remnants of four almost equally bright elliptical galaxies within a core of radius 10 kpc. Such corrugation of the stellar distribution is very rare, andExpand
Gravitational hydrodynamics of large-scale structure formation
The gravitational hydrodynamics of the primordial plasma with neutrino hot dark matter is considered as a challenge to the bottom-up cold-dark-matter paradigm. Viscosity and turbulence induce aExpand
Constraining dark matter models from a combined analysis of Milky Way satellites with the Fermi Large Area Telescope.
This work presents a search for dark matter consisting of weakly interacting massive particles, applying a joint likelihood analysis to 10 satellite galaxies with 24 months of data of the Fermi Large Area Telescope, and is able to rule out models with the most generic cross section, using gamma rays.

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,283 new measurements from 899 Japers, we list, evaluate, and average measured properties ofExpand
Searching for the missing baryons in clusters
It is shown that the baryons may not actually be missing from clusters, but rather are extended to larger radii than typically observed, and reaches the cosmic value near the virial radius for all groups and clusters above. Expand
