Velocity peaks and caustic rings

Dark Matter Caustics

In a recent study of 32 extended and well-measured galactic rotation curves, evidence for the self-similar model of galactic halo formation predicts that the caustic ring radii a(n) follow the approximate law a( n) approximately 1/n.

Resolving infall caustics in dark matter halos

It has been found that the phase space of dark matter particles assembling a galactic halo in cosmological N-body simulations well defines the fine grained structure. Recently accreted particles form…

Testing universal dark-matter caustic rings with galactic rotation curves

. Infall of cold dark matter on a galaxy may result in caustic rings where the particle density is enhanced. They may be searched for as features in the galactic rotation curves. Previous studies…

Does the second caustic ring of dark matter cause the Monoceros Ring of stars

Caustic rings of dark matter were predicted to exist in the plane of the Galaxy at radii a n ≃ 40 kpc /n for n = 1, 2, 3,.... The recently discovered Monoceros Ring of stars is located near the n = 2…

Dark matter caustics in galaxy clusters

Results of a search for cold flows of dark matter axions.

Limits are placed on the density of any local flow of axions as a function of the flow velocity dispersion over the axion mass range 1.98 to 2.17 microeV.

Effects of a caustic ring of dark matter on the distribution of stars and interstellar gas

Caustic rings of dark matter with $\textit{tricusp}$ cross-section were predicted to lie in the galactic disk. Their radii increase on cosmological time scales at a rate of order $1$ kpc/Gyr. When a…

Robustness of Discrete Flows and Caustics in Cold Dark Matter Cosmology

Although a simple argument implies that the distribution of dark matter in galactic halos is characterized by discrete flows and caustics, their presence is often ignored in discussions of galactic…

The Secondary infall model of galactic halo formation and the spectrum of cold dark matter particles on earth

The spectrum of cold dark matter particles on Earth is expected to have peaks in velocity space associated with particles which are falling onto the Galaxy for the first time and with particles which…

Distribution of dark matter in the spiral galaxy NGC 3198.

Two-component mass models, consisting of an exponential disk and a spherical halo, are constructed to fit a newly determined rotation curve of NGC 3198 that extends to 11 disk scale lengths. The…

Self-similar secondary infall and accretion in an Einstein-de Sitter universe

Similarity solutions have been found for secondary infall and accretion onto an initially overdense perturbation in an Einstein--de Sitter (..cap omega.. = 1) universe. After the initial collapse of…

Self-similar gravitational collapse in an expanding universe

We derive similarity solutions which describe the collapse of cold, collisionless matter in a perturbed Einstein-de Sitter universe. We obtain three classes of solutions, one each with planar,…
