Impact of Few-Body Reactions on Explosive Nucleosynthesis: The Big-Bang and Supernovae
Toshitaka Kajino, Kaori Otsuki, Shin-ya Wanajo +2
We study the few body reactions in explosive nucleosynthesis of light-to-heavy mass elements in various astrophysical conditions. In neutrino-driven winds of gravitational core col…

Neutrino Degeneracy and Decoupling: New Limits from Primordial Nucleosynthesis and the Cosmic Microwave Background
M. Orito, T. Kajino, G. J. Mathews +1
We reanalyze the cosmological constraints on the existence of a net universal lepton asymmetry and neutrino degeneracy. We show that neutrinos can begin to decouple at higher tempe…

A Search for Sub-TeV Gammas in Coincidence with Gamma Ray Bursts
J. Poirier, C. D'Andrea, P. C. Fragile +3
We report on a study of sub-TeV ( GeV) gamma-ray-induced muon secondaries in coincidence with BATSE gamma ray bursts (GRBs). Each TeV gamma ray striking the atmosphere pro…
