Neutrino Spectral Pinching in 3D Core-Collapse Supernovae: Late-Time Convergence, Failed-Explosion Signatures, and Viewing-Angle Dispersion
The episode discusses a paper on neutrino spectral pinching in 3D core-collapse supernovae, focusing on late-time convergence and failed-explosion signatures. Researchers found a late-time floor for the electron antineutrino pinching parameter at 1.92 ± 0.10 for long models and noted anti-pinching in black hole forming models before collapse.
