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 larger than the observed baryonic mass in the form of hot gas and stars in galaxies. Here I consider further the suggestion that the undetected matter might be in the form of cosmological neutrinos with mass of the order of 2 eV. If the neutrinos and baryons have comparable velocity dispersions and… Expand

Neutrinos as galactic dark matter in the Ursa Major galaxy group
We present the analysis of 23 published rotation curves of disc galaxies belonging to the Ursa Major group of galaxies, with kinematics free of irregularities. The rotation curves are analysed in theExpand
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
MOND and neutrinos: The dark matter density-temperature diagram for X-ray clusters
Abstract Neutrinos have been postulated as a major contributor to the mass of galaxy clusters, particularly in the framework of Modified Newtonian Dynamics (MOND). Recent X-ray and gravitationalExpand
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 sterileExpand
Weak Lensing of Galaxy Clusters in Modified Newtonian Dynamics
We study weak gravitational lensing of galaxy clusters in terms of the MOND (modified Newtonian dynamics) theory. We calculate shears and convergences of background galaxies for three clustersExpand
Necessity of dark matter in modified Newtonian dynamics within galactic scales.
It is concluded that strong gravitational lensing on galactic scales requires a significant amount of dark matter, even within MOND, unless lensing is qualitatively different within a covariant, such as Tensor-Vector-Scalar (TeVeS), theory. Expand
Forming galaxies with MOND
Beginning with a simple model for the growth of structure, I consider the dissipationless evolution of a MOND-dominated region in an expanding universe by means of a spherically symmetric N-bodyExpand
Reconciling MOND and dark matter
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 ofExpand
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
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. Expand


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
Mixed Dark Matter Model in Halos of Clusters
We discuss the structure of clusters in a class of flat cosmological models with the fraction of mass \Omega_{CDM} ~0.8 in cold dark matter, and the rest in hot dark matter in the form of massiveExpand
Clusters of galaxies with modified Newtonian dynamics
I consider X-ray emitting clusters of galaxies in the context of modified Newtonian dynamics (MOND). Self-gravitating isothermal gas spheres are not good representations of rich clusters; the X-rayExpand
The thermal imprint of galaxy formation on X-ray clusters
It is widely believed that structure in the Universe evolves hierarchically—fluctuations in the primordial distribution of matter, amplified by gravity, collapse and merge to form progressivelyExpand

Firm bounds on the neutrino mass from the distribution of dark matter in galaxies
We explore the possibility that the dark or missing matter in galaxies is due to massive neutrinos. Two approaches are described which give lower mass limits for a single neutrino type in terms ofExpand

The statistical mechanical investigation of violent relaxation (first introduced by Lynden-Bell in 1967) is extended to indistinguishable objects. It is found that, coincidentally, the equilibriumExpand
