Why a ring of stars at r = 20 kpc?
Pierre Sikivie
The recently discovered ring of stars near Galactocentric distance kpc is interpreted as baryonic matter accreted onto the second caustic ring of dark matter in our galaxy…
The cold axion populations
S. Chang, C. Hagmann, P. Sikivie
We give a systematic discussion of the contributions to the cosmological energy density in axions from vacuum realignment, string decay and wall decay. We call these the cold axion…

Contents: 1. The strong CP problem 2. Dark matter axions 3. The cavity detector of galactic halo axions 4. The phase space structure of cold dark matter halos
A 2nd generation cosmic axion experiment
C. Hagmann, W. Stoeffl, K. van Bibber +11
An experiment is described to detect dark matter axions trapped in the halo of our galaxy. Galactic axions are converted into microwave photons via the Primakoff effect in a static…
