Dark matter, proposed decades ago as a speculative component of the universe, is now known to be the vital ingredient in the cosmos: six times more abundant than ordinary matter, one-quarter of the total energy density, and the component that has controlled the growth of structure in the universe. Its nature remains a mystery, but assuming that it is composed of weakly interacting subatomic particles, is consistent with large-scale cosmic structure. However, recent analyses of structure on… 

Dark Matter in Modern Cosmology

The presence of Dark Matter is required in the Universe regulated by the standard general relativistic theory of gravitation. The nature of Dark Matter is however still elusive to any experimental


The latest cosmological data point to a model of the universe that is self-consistent but deeply weird. It seems that most matter in our universe is non-baryonic and hidden from direct view.

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

Minimum mass of galaxies from BEC or scalar field dark matter

Many problems of cold dark matter models such as the cusp problem and the missing satellite problem can be alleviated, if galactic halo dark matter particles are ultra-light scalar particles and in

The Role of the ILC in the Study of Cosmic Dark Matter

Though there is strong evidence that dark matter is a major component of the universe, most aspects of dark matter are completely mysterious. We do not know what dark matter is, and we do not know

A brief Review of the Scalar Field Dark Matter model

In the last time the cold dark matter (CDM) model has suggested more and more that it is not able to describe all the properties of nearby galaxies that can be observed in great detail as well as

On the mass of ultra-light bosonic dark matter from galactic dynamics

We consider the hypothesis that galactic dark matter is composed of ultra-light scalar particles and use internal properties of dwarf spheroidal galaxies to establish a preferred range for the mass

The Observed Properties of Dark Matter on Small Spatial Scales

A synthesis of recent photometric and kinematic data for several of the most dark matter dominated galaxies, the dwarf spheroidal Galactic satellites, and compare them to star clusters provides new information about the nature of the dominant form of dark matter.

On the mass of ultra-light bosonic dark matter from galactic dynamics

We consider the hypothesis that galactic dark matter is composed of ultra-light scalar particles and use internal properties of dwarf spheroidal galaxies to establish a preferred range for the mass m



Throwing Light on Dark Energy

New observational programs can trace the history of cosmic expansion more precisely and over a larger span of time than has been done to date to learn whether the dark energy is a modern version of Einstein's cosmological constant or another form of dark energy that changes with time.

Fuzzy cold dark matter: the wave properties of ultralight particles.

These problems might be solved, and the virtues of CDM models retained, even without postulating ad hoc dark matter particle or field interactions, if the dark matter is composed of ultralight scalar particles initially in a (cold) Bose-Einstein condensate, similar to axion dark matter models.

The cosmological constant and cold dark matter

THE cold dark matter (CDM) model1–4 for the formation and distribution of galaxies in a universe with exactly the critical density is theoretically appealing and has proved to be durable, but recent

Decaying Cold Dark Matter Model and Small-Scale Power

The canonical cosmological constant-dominated cold dark matter model (ΛCDM) may possess too much power on small scales at z = 0, manifested as central overconcentration of dark matter and

Observational evidence for self-interacting cold dark matter

Astronomical observations may enable us to study dark matter properties that are inaccessible in the laboratory if the cold dark matter particles are self-interacting with a large scattering cross section but negligible annihilation or dissipation.

Halo Formation in Warm Dark Matter Models

Discrepancies have emerged between the predictions of standard cold dark matter (CDM) theory and observations of clustering on subgalactic scales. Warm dark matter (WDM) is a simple modification of

The Core Density of Dark Matter Halos: A Critical Challenge to the ΛCDM Paradigm?

We compare the central mass concentration of cold dark matter (CDM) halos found in cosmological N-body simulations with constraints derived from the Milky Way disk dynamics and from the Tully-Fisher

Annihilating cold dark matter

P plausible scenarios for avoiding the early Universe annihilation catastrophe that could result from such a large cross section of CDM particles, which seems consistent with observations.

The observational case for a low-density Universe with a non-zero cosmological constant

OBSERVATIONS are providing progressively tighter constraints on cosmological models advanced to explain the formation of large-scale structure in the Universe. These include recent determinations of

Weakly Self-interacting Dark Matter and the Structure of Dark Halos

We study the formation of dark halos in a ΛCDM universe under the assumption that cold dark matter (CDM) particles have a finite cross section for elastic collisions. We compare evolution when CDM
