Black Hole Entropy Constraints on Variation of the Gravitational Constant
Jane H MacGibbon
Here we apply the Generalized Second Law of Thermodynamics (GSL) to black holes accreting and emitting in the present Universe and derive upper limits on the variation in the gravi…
Black Hole Constraints on Varying Fundamental Constants
Jane H MacGibbon
Here we apply the Generalized Second Law of Thermodynamics and derive upper limits on the variation in the fundamental constants. The maximum variation in the electronic charge per…
Tau Neutrinos from Astrophysical and Cosmological Sources
Jane H. MacGibbon, Ubi F. Wichoski, Bryan R. Webber
Previous work on the neutrino spectra from high energy sources has not included the tau neutrinos directly produced by the decays in the source. Here we consider the tau neutrino c…
High Energy Fluxes from a Non-Scaling Cosmic String Network
U. F. Wichoski, R. H. Brandenberger, J. H. MacGibbon
Topological defects, particularly cosmic strings, can provide a mechanism to produce particles with energies of the order 10^21 eV and higher. Here, we report on order of magnitude…
