Temporal and Angular Variations of 3D Core-Collapse Supernova Emissions and their Physical Correlations

Understand

We provide the time series and angular distributions of the neutrino and gravitational-wave emissions of eleven state-of-the-art three-dimensional non-rotating core-collapse supernova models and explore correlations between these signatures and the real-time dynamics of the shock and the proto-neutron-star core.

• The neutrino emissions are roughly isotropic on average, with instantaneous excursions about the mean inferred luminosity of as much as $\pm$20%.
• The deviation from isotropy is least for the "$\nu_{\mu}$"-type neutrinos and the lowest-mass progenitors.
• Instantaneous temporal luminosity variations along a given direction for exploding models average $\sim$2$-$4%, but can be as high as $\sim$10%.
