TL;DR: The neutrino emission characteristics of the first full-scale three-dimensional supernova simulations with sophisticated three-flavor neutrinos transport for three models with masses 11.2, 20, and $27{M}

TL;DR: The new code ALCAR developed to model multidimensional, multi energy-group neutrino transport in the context of supernovae and neutron-star mergers is presented, which is significantly more efficient than a multiddimensional solver of the Boltzmann equation and more accurate and consistent than the flux-limited diffusion method.

TL;DR: In this paper, a detailed theoretical analysis of the post-bounce evolution of core-collapse supernovae (SNe) is presented, employing for the first time relativistic, two-dimensional (2D) explosion models with multi-group, three-flavor neutrino transport based on the ray-by-ray-plus approximation.

TL;DR: The appearance of muons softens the NS equation of state, triggers faster NS contraction, and thus leads to higher luminosities and mean energies of the emitted neutrinos, which strengthens the postshock heating by neutrines and can facilitate explosions by the neutrino-driven mechanism.

TL;DR: In this article, it was shown that the distribution of black hole kick velocities should be similar to that of neutron stars, and that the acceleration of new-born neutron stars can be accelerated by anisotropic neutrino emission of the nascent neutron star.
