Projection and Galaxy Clustering Fourier Spectra
J. N. Fry, David Thomas
Second order perturbation theory predicts a specific dependence of the bispectrum, or three-point correlation function in the Fourier transform domain, on the shape of the configur…
Generalized Limits to the Number of Light Particle Degrees of Freedom from Big Bang Nucleosynthesis
Keith A. Olive, David Thomas
We compute the big bang nucleosynthesis limit on the number of light neutrino degrees of freedom in a model-independent likelihood analysis based on the abundances of He4 and Li7.…
A Big Bang Nucleosynthesis Likelihood Analysis of the Baryon-to-Photon Ratio and the Number of Light Particle Degrees of Freedom
Keith A. Olive, David Thomas
We extend the model-independent likelihood analysis of big bang nucleosynthesis (BBN) based on He4 and Li7 to allow for numbers of degrees of freedom which differ from the standard…
Model Independent Predictions of Big Bang Nucleosynthesis from \he4 and \li7: Consistency and Implications
Brian D. Fields, Kimmo Kainulainen, Keith A. Olive +1
We examine in detail how BBN theory is constrained, and what predictions it can make, when using only the most model-independent observational constraints. We avoid the uncertainti…
Monte-Carlo Analysis of Big Bang Production of Beryllium and Boron
David Thomas
There is continued interest in the possibility that big bang nucleosynthesis may produce significant quantities of Be and B. In this paper we reevaluate the primordial abundances t…
Predicting Big Bang Deuterium
N. Hata, R. J. Scherrer, G. Steigman +2
We present new upper and lower bounds to the primordial abundances of deuterium and helium-3 based on observational data from the solar system and the interstellar medium. Independ…
