An Approach to Neutrino Radiative Transfer in Supernova Simulations
Christian Y. Cardall
Neutrinos dominate the energetics of core-collapse supernovae, and are believed to play an important role in driving the explosion. The development of a spatially multidimensional…
NewtonPlus: Approximating Relativistic Effects in Supernova Simulations
Christian Y. Cardall, Anthony Mezzacappa
We propose an approximation to full relativity that captures the main gravitational effects of dynamical importance in supernovae. The conceptual link between this formalism and th…
NewtonPlus: Approximate Relativity for Supernova Simulations
Christian Y. Cardall, Anthony Mezzacappa, Matthias Liebendoerfer
We propose an approximation to general relativity that captures the main gravitational effects of dynamical importance in supernovae. The conceptual link between this formalism and…
Semianalytic Analysis of Primordial Black Hole Formation During a First-order QCD Phase Transition
Christian Y. Cardall, George M. Fuller
It has recently been suggested that cosmologically significant numbers of black holes could form during a first-order QCD phase transition. Further, it has been asserted that these…
Neutrino Physics and the Primordial Elemental Abundances
Christian Y. Cardall, George M. Fuller
Limits can be placed on nonstandard neutrino physics when big bang nucleosynthesis (BBN) calculations employing standard neutrino physics agree with the observationally inferred pr…
