The evidence for the dark matter (DM) of the hot big bang cosmology is about as good as it gets in natural science. The exploration of its nature is now led by direct and indirect detection experiments, to be complemented by advances in the full range of cosmological tests, including judicious consideration of the rich phenomenology of galaxies. The results may confirm ideas about DM already under discussion. If we are lucky, we also will be surprised once again.

Its existence requires an extension of the current understanding of particle physics or otherwise point to a modification of gravity on cosmological scales.

Merger of dark matter axion clumps and resonant photon emission

A portion of light scalar dark matter, especially axions, may organize into gravitationally bound clumps (stars) and be present in large number in the galaxy today. It is therefore of utmost interest

A Philosophical Approach to MOND: Assessing the Milgromian Research Program in Cosmology

Dark matter is a fundamental component of the standard cosmological model, but in spite of four decades of increasingly sensitive searches, no-one has yet detected a single dark-matter particle in

In the past few years, the search for axion-like particles (ALPs) has grown significantly due to their potential to account for the total abundance of the cold dark matter (CDM) in the universe. The

Scalar dark matter clumps with angular momentum

The behavior of light scalar dark matter has been a subject of much interest recently as it can lead to interesting small scale behavior. In particular, this can lead to the formation of

Distribution of phantom dark matter in dwarf spheroidals

We derive the distribution of the phantom dark matter in the eight classical dwarf galaxies surrounding the Milky Way, under the assumption that modified Newtonian dynamics (MOND) is the correct

Production of GeV-scale heavy neutral leptons in three-body decays. Comparison with the PYTHIA approach

Despite the undeniable success of the Standard Model of particle physics (SM), there are some phenomena that the SM can't explain. These phenomena indicate that the SM has to be modified. One of the

CLUMP-3D: Testing ΛCDM with Galaxy Cluster Shapes

The ΛCDM model of structure formation makes strong predictions on the concentration and shape of dark matter (DM) halos, which are determined by mass accretion processes. Comparison between predicted

Obtaining a scalar fifth force via a symmetry-breaking coupling between the scalar field and matter

A matter-coupled scalar field model is presented to obtain a scalar fifth force when the constraint of the current cosmological constant is satisfied. The interaction potential energy density between

Could trapped quintessence account for the laser-detuning-dependent acceleration of cold atoms in varying-frequency time-of-flight experiments?

Using a trapped quintessence model, a series of time-of-flight (TOF) experiments with a different frequency of probe light were designed and performed. The varying-frequency TOF (VFTOF) experiments



Search for dark-matter particles

The astrophysical studies which bear on the density and the phase-space structure of the dark-matter particles are reviewed; the implications of the various direct and indirect searches for these particles are discussed; and alternative suggestions for the candidates and directions for further searches are pointed out.

The baryon content of galaxy clusters: a challenge to cosmological orthodoxy

Baryonic matter constitutes a larger fraction of the total mass of rich galaxy clusters than is predicted by a combination of cosmic nucleosynthesis considerations (light-element formation during the

Finding the Big Bang

The story of the discovery and exploration of the CMBR in the 1960s is recalled for the first time in this collection of 44 essays by eminent scientists who pioneered the work.

Challenges for ΛCDM and MOND

The Universe on large scales is well described by the ΛCDM cosmological model. There however remain some heavy clouds on our global understanding, especially on galaxy scales, which we review here.

Tests of Cosmological Models Constrained by Inflation

The inflationary scenario requires that the universe have negligible curvature along constant-density surfaces. In the Friedmann-Lemaitre cosmology that leaves us with two free parameters, Hubble's


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 correlation


It has long been regarded as difficult if not impossible for a cosmological model to account simultaneously for the galaxy luminosity, mass, and velocity distributions. We revisit this issue using a

Chandra measurements of a complete sample of X-ray luminous galaxy clusters: the gas mass fraction

We present Chandra X-ray measurements of the gas mass fraction out to r500 for a complete sample of the 35 most luminous clusters from the Brightest Cluster Sample and the Extended Brightest Cluster

An unbound universe

A variety of arguments strongly suggest that the density of the universe is no more than a tenth of the value required for closure. Loopholes in this reasoning may exist, but if so, they are
