"Just So" Neutrino Oscillations Are Back
Sheldon L. Glashow, Peter J. Kernan, Lawrence M. Krauss
Recent evidence for oscillations of atmospheric neutrinos at Super-Kamiokande suggest, in the simplest see-saw interpretation, neutrino masses such that `just so' vacuum oscillatio…
The Age Of Globular Clusters In Light Of Hipparcos: Resolving the Age Problem?
Brian Chaboyer, P. Demarque, Peter J. Kernan +1
We review five independent techniques which are used to set the distance scale to globular clusters, including subdwarf main sequence fitting utilizing the recent Hipparcos paralla…
Comment on ``Constraints on the strength of primordial B-fields from big bang nucleosynthesis reexamined''
Peter J. Kernan, Glenn D. Starkman, Tanmay Vachaspati
Recently Cheng, Olinto, Schramm and Truran (COST) reexamined the constraints from big bang nucleosynthesis (BBN) on the strength of primordial magnetic fields. Their bottom line ag…
A Precision Age Determination Technique for Globular Clusters
Brian Chaboyer, Pierre Demarque, Peter Kernan +2
Globular cluster age estimates based on the absolute magnitude of the main sequence turn-off (\mvto) are generally considered to be the most reliable from a theoretical viewpoint.…
Big Bang Nucleosynthesis Constraints on Primordial Magnetic Fields
Peter. J. Kernan, Glenn D. Starkman, Tammay Vachaspati
We reanalyze the effect of magnetic fields in BBN, incorporating several features which were omitted in previous analyses. We find that the effects of coherent magnetic fields on t…
A Lower Limit on the Age of the Universe
Brian Chaboyer, Peter J. Kernan, Lawrence M. Krauss +1
We report the results of a detailed numerical study designed to estimate both the absolute age and the uncertainty in age (with confidence limits) of the oldest globular clusters.…
