Image Ellipticity from Atmospheric Aberrations
W. H. de Vries, S. S. Olivier, S. J. Asztalos +2
We investigate the ellipticity of the point-spread function (PSF) produced by imaging an unresolved source with a telescope, subject to the effects of atmospheric turbulence. It is…
Properties of Ellipticity Correlation with Atmospheric Structure from Gemini South
S. Asztalos, W. H. de Vries, L. J Rosenberg +5
Cosmic shear holds great promise for a precision independent measurement of , the mass density of the universe relative to the critical density. The signal is expected to b…
A High Resolution Search for Dark-Matter Axions
L. D. Duffy, P. Sikivie, D. B. Tanner +7
We have performed a high resolution search for galactic halo axions in cold flows using a microwave cavity detector. The analysis procedure and other details of this search are des…
Big-Bang nucleosynthesis (Particle Data Group mini-review)
Brian Fields, Subir Sarkar
A critical review is given of the current status of cosmological nucleosynthesis. In the framework of the Standard Model with 3 types of relativistic neutrinos, the baryon-to-photo…
Results of a Search for Cold Flows of Dark Matter Axions
L. Duffy, P. Sikivie, D. B. Tanner +7
Theoretical arguments predict that the distribution of cold dark matter in spiral galaxies has peaks in velocity space associated with non-thermalized flows of dark matter particle…
An Improved RF Cavity Search for Halo Axions
S. J. Asztalos, R. F. Bradley, L. Duffy +10
The axion is a hypothetical elementary particle and cold dark matter candidate. In this RF cavity experiment, halo axions entering a resonant cavity immersed in a static magnetic f…
