Diurnal
and Annual Modulation of Cold Dark Matter Signals. FuSin
Ling, P. Sikivie and S. Wick (2004) derive the diurnal and annual modulation
signatures of a cold dark matter flow in axion and WIMP direct detection
experiments, taking account not only of the orbital motion of the Earth,
but also the gravity of the Sun, the rotation of the Earth and the gravitational
field of the Earth.

Evidence
for Ring Caustics in the Milky Way. P.Sikivie (2003) finds evidence
for caustic rings of dark matter in the Milky Way, again with radii obeying
the a_n \propto 1/n law. The evidence is based upon the existence
of sharprises in the rotation curve of our galaxy and on the appearance
of a triangular feature in an IRAS map of the Galactic plane.

Evidence
for universal structure in galactic halos. W.H. Kinney and P.Sikivie
(2000) analyze the rotation curves of 32 external galaxies and finds evidence
for caustic rings of dark matter with radii obeying the a_n \propto 1/n
law.

The
caustic ring singularity. P. Sikivie (1999) gives a detailed
description of the structure of caustic rings of dark matter in terms of
the elliptic umbilic catastrophe, emphasizes that caustics will be present
in cold dark matter halos for general modelindependent reasons.

The
geometry of phase mixing. S.Tremaine (1999) discusses the expected
dimensionality of phasespace structures and suggests that the most prominent
features in surveys with K>=D (where D is the dimensionally of the phase
structure and K is the number of observables) will be stable singularities
(catastrophes).

Caustic
rings of dark matter. P. Sikivie (1998) shows the existence
of inner caustics in dark matter halos, describes them as caustic rings,
gives a law (a_n \propto 1/n) for the caustic ring radii in the case of
selfsimilar infall, points to observational evidence for caustic rings
of dark matter.

flows of dark matter and caustics are a direct consequence of this phasespace
structure.
