Assessing Big-Bang Nucleosynthesis
Craig J. Copi, David N. Schramm, Michael S. Turner
Systematic uncertainties in the light-element abundances and their evolution make a rigorous statistical assessment difficult. However, using Bayesian methods we show that the foll…
Implications of a High Population II B/Be Ratio
B. Fields, K. Olive, D. Schramm
The observed B/Be ratio in extreme Pop II stars has been interpreted as evidence of Be and B synthesis by early galactic cosmic rays. However, a recent reanalysis of the boron abun…
Big-Bang Nucleosynthesis and the Baryon Density of the Universe
Craig J Copi, David N. Schramm, Michael S. Turner
Big-bang nucleosynthesis is one of the cornerstones of the standard cosmology. For almost thirty years its predictions have been used to test the big-bang model to within a fractio…
Testing for Gaussianity Through the Three Point Temperature Correlation Function
Xiaochun Luo, D. N. Schramm
One of the crucial aspects of density perturbations that are produced by the standard inflation scenario is that they are Gaussian where seeds produced by topological defects tend…
Constraints on Dirac Neutrinos from SN 1987A
R. Mayle, D. N. Schramm, M. S. Turner +1
The Livermore Supernova Explosion Code was used to calculate the effect of a massive Dirac neutrino on neutrino emission from SN 1987A in a fully self-consistent manner. Spin-flip…
