Comprehensive neutrino light curves and spectra: from pre-supernova evolution to early supernova phase
Chinami Kato, Hiroki Nagakura, Akira Ito +4
We present the first systematic study of neutrino emissions from massive stars, continuously tracking the late evolutionary stages through the early core-collapse supernova phase.…

A Dual-Resolution Prescription in the Method for Boltzmann Neutrino Transport I: Proof of Principle and the Resolution of Collision Term
Akira Ito, Ryuichiro Akaho, Hiroki Nagakura +1
We propose a dual-resolution prescription meant for the Boltzmann neutrino transport, in which the advection and collision terms are calculated with different angular resolutions i…
