6 questions
First-principles completion of Bethe's delayed-neutrino supernova model: convective energy transport, mass fallback, and the neutron-star/black-hole boundary
Controlled irreducible kernels and an intrinsic bound-state criterion for the covariant two-body equation: the open core of the 1951 Salpeter–Bethe program
Empirical anchoring of the Galactic rates and observability of merging neutron-star-black-hole and binary-neutron-star systems: the five model uncertainties flagged by Bethe and Brown (1998)
Open issues of Bethe's analytic supernova-shock theory: the breakout energy, its progenitor dependence, and the crossover between visible and failed supernovae
Open questions from Bethe's 'Supernova Shock. VIII.' (1997): fallback, the compact remnant, and Fe-group yields of the neutrino-driven explosion of SN 1987A
Complete-experiment reconstruction of the nucleon-nucleon elastic scattering matrix at fixed energy and angle, and the discrete ambiguities that survive complete sets of polarization observables
