A rare coincidence of scales in standard particle physics is needed to explain why Λ or the negative pressure of cosmological dark energy (DE) coincides with the positive pressure P0 of random motion of dark matter (DM) in bright galaxies. Recently Zlosnik and coworkers proposed to modify the Einstein curvature by adding nonlinear pressure from a medium flowing with a four-velocity vector field Uμ. We propose to check whether a smooth extension of general relativity with a simple kinetic… Expand
Perturbations In A Non-Uniform Dark Energy Fluid: Equations Reveal Effects of Modified Gravity and Dark Matter
We propose a unified single-field description of the galactic Dark Matter and various uniform scalar fields for the inflation and cosmological constant. The two types of effects could originate fromExpand
Model of Dark Matter and Dark Energy Based on Gravitational Polarization
A model of dark matter and dark energy based on the concept of gravitational polarization is investigated. We propose an action in standard general relativity for describing, at some effective orExpand
ON THE SEPARATION BETWEEN BARYONIC AND DARK MATTER: EVIDENCE FOR PHANTOM DARK MATTER?
The recent years have seen combined measurements of X-ray and (weak) lensing contours for colliding galaxy clusters such as, for instance, the famous 'Bullet' cluster. These observations haveExpand
Cosmological electromagnetic fields and dark energy
We show that the presence of a temporal electromagnetic field on cosmological scales generates an effective cosmological constant which can account for the accelerated expansion of the universe.Expand
GALAXY BULGES AS TESTS OF CDM VERSUS MOND IN STRONG GRAVITY
The tight correlation between galaxy bulges and their central black hole masses likely emerges in a phase of rapid collapse and starburst at high redshift, due to the balance of gravity on gas withExpand
MOND plus classical neutrinos are not enough for cluster lensing
Clusters of galaxies offer a robust test bed for probing the nature of dark matter that is insensitive to the assumption of the gravity theories. Both Modified Newtonian Dynamics (MOND) and GeneralExpand
An ecological approach to problems of Dark Energy, Dark Matter, MOND and Neutrinos
Modern astronomical data on galaxy and cosmological scales have revealed powerfully the existence of certain dark sectors of fundamental physics, i.e., existence of particles and fields outside theExpand
THE WEDDING OF MODIFIED DYNAMICS AND NON-EXOTIC DARK MATTER IN GALAXY CLUSTERS
We summarize the status of Modified Newtonian Dynamics (MOND) in galaxy clusters. The observed acceleration is typically larger than the acceleration threshold of MOND in the central regions,Expand
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 modifiedExpand
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

Insight into the baryon-gravity relation in galaxies
Observations of spiral galaxies strongly support a one-to-one analytical relation between the inferred gravity of dark matter at any radius and the enclosed baryonic mass. It is baffling that baryonsExpand
A tensor—vector—scalar framework for modified dynamics and cosmic dark matter
I describe a tensor-vector-scalar theory that reconciles the galaxy-scale success of modified Newtonian dynamics (MOND) with the cosmological scale evidence for cold dark matter (CDM). The theoryExpand
Tidal dwarf galaxies as a test of fundamental physics
Within the cold dark matter (CDM) framework tidal dwarf galaxies (TDGs) cannot contain dark matter, so the recent results by Bournaud et al. (2007, Science, 316, 1166) that 3 rotating TDGs do showExpand
Maximum feedback and dark matter profiles of dwarf galaxies
The observed rotation curves of dark matter-dominated dwarf galaxies indicate low-density cores, contrary to the predictions of CDM models. A possible solution of this problem involves stellarExpand

There is evidence that Newton and Einstein's theories of gravity cannot explain the dynamics of a universe made up solely of baryons and radiation. To be able to understand the properties ofExpand

We present a simple scenario where the formation of galactic bulges was regulated by the dark halo gravity and regulates the growth of the central supermassive black hole. Assuming the angularExpand

TLDR
