Fast Neutrino Flavor Instability in the Neutron-star Convection Layer of Three-dimensional Supernova Models

1 code implementation30 Nov 2019 Robert Glas, H. -Thomas Janka, Francesco Capozzi, Manibrata Sen, Basudeb Dasgupta, Alessandro Mirizzi, Guenter Sigl

The transport solution does not provide the angular distributions of the neutrino fluxes, which are crucial to track the fast flavor instability.

Probing Intergalactic Magnetic Fields with Simulations of Electromagnetic Cascades

4 code implementations1 Jul 2016 Rafael Alves Batista, Andrey Saveliev, Guenter Sigl, Tanmay Vachaspati

We determine the effect of intergalactic magnetic fields on the distribution of high energy gamma rays by performing three-dimensional Monte Carlo simulations of the development of gamma-ray-induced electromagnetic cascades in the magnetized intergalactic medium.
