Observations of galaxies suggest a one-to-one analytic relation between the inferred gravity of dark matter at any radius and the enclosed baryonic mass, a relation summarized by Milgrom's law of modified Newtonian dynamics (MOND). However, present-day covariant versions of MOND usually require some additional fields contributing to the geometry, as well as an additional hot dark matter component to explain cluster dynamics and cosmology. Here, we envisage a slightly more mundane explanation… 
Alternative to particle dark matter
We propose an alternative to particle dark matter that borrows ingredients of MOdified Newtonian Dynamics (MOND) while adding new key components. The first new feature is a dark matter fluid, in the
Extended LCDM: generalized non-minimal coupling for dark matter fluids
In this paper we discuss a class of models that address the issue of explaining the gravitational dynamics at the galactic scale starting from a geometric point of view. Instead of claiming the
Modified Newtonian Dynamics (MOND): Observational Phenomenology and Relativistic Extensions
It is shown that many of these puzzling observations are predicted by one single relation — Milgrom’s law — involving an acceleration constant a0 on the order of the square-root of the cosmological constant in natural units.
Non-minimally coupled dark matter: effective pressure and structure formation
We propose a phenomenological model in which a non-minimal coupling between gravity and dark matter is present in order to address some of the apparent small scales issues of ΛCDM model. When
Theory of dark matter superfluidity
We propose a novel theory of dark matter (DM) superfluidity that matches the successes of the Λ cold dark matter (ΛCDM) model on cosmological scales while simultaneously reproducing the modified

A test using gas rich galaxies for which both axes of the BTFR can be measured independently of the theories being tested and without the systematic uncertainty in stellar mass that affects the same test with star dominated spirals is reported.
Local-Group tests of dark-matter concordance cosmology - Towards a new paradigm for structure formation
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
Equilibrium configurations of 11 eV sterile neutrinos in MONDian galaxy clusters
Modified Newtonian Dynamics (MOND) can fit a broad range of galaxy kinematic data, but struggles with clusters of galaxies. MONDian clusters need dark matter, and here we test the 11 eV/c 2 sterile
Dark Matter Superfluidity
In this talk I summarize a novel framework that unifies the stunning success of MOND on galactic scales with the triumph of the $\Lambda$CDM model on cosmological scales. This is achieved through the
Dark matter as a Bose--Einstein Condensate: the relativistic non-minimally coupled case
Bose--Einstein Condensates have been recently proposed as dark matter candidates. In order to characterise the phenomenology associated to such models, we extend previous investigations by studying


Marriage à-la-MOND: Baryonic dark matter in galaxy clusters and the cooling flow puzzle
Abstract I start with a brief introduction to MOND phenomenology and its possible roots in cosmology—a notion that may turn out to be the most far reaching aspect of MOND. Next I discuss the
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 baryons
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 show
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 or
Do modified Newtonian dynamics follow from the cold dark matter paradigm
In a recent paper, Kaplinghat & Turner (KT) advertised that modified Newtonian dynamics (MOND) could be derived naturally in the cold dark matter (CDM) paradigm. They actually proceeded to produce a
On the Law of Gravity, the Mass of Neutrinos and the Proof of Dark Matter
We fit the weak lensing map of the bullet merging galaxy cluster 1E 0657-56 in a class of gravity theories interpolating between GR and MOND (General Relativity and Modified Newtonian Dynamics), so
Modified Newtonian dynamics as an alternative to dark matter
▪ Abstract Modified Newtonian dynamics (MOND) is an empirically motivated modification of Newtonian gravity or inertia suggested by Milgrom as an alternative to cosmic dark matter. The basic idea is
Neutrinos as cluster dark matter
The dynamical mass of clusters of galaxies, calculated in terms of MOdified Newtonian Dynamics (MOND), is a factor of 2 or 3 times smaller than the Newtonian dynamical mass but remains significantly
Field-theoretical formulations of MOND-like gravity
Modified Newtonian dynamics (MOND) is a possible way to explain the flat galaxy rotation curves without invoking the existence of dark matter. It is, however, quite difficult to predict such a
A review on success and problem of MOND on globular cluster scale
Many past attempts to kill MOND have only strengthened the theory. Better data on galaxy velocity curves clearly favor MOND (without fine-tuning) over cold dark matter. The usual critism on the
