3D MHD simulations of pre-supernova progenitors find turbulent mixing in oxygen and silicon shells deviates from standard 1D mixing-length prescriptions, with proposed updates for stellar evolution codes.
Higher-Mach-number self-similar shock solutions in failed supernovae are unstable and strengthen asymptotically above a critical neutrino mass-loss threshold, explaining greater ejection in red supergiants versus compact progenitors.
Black hole supernovae occur across a wide progenitor mass range from 19.5 to 60 solar masses, yielding final black hole masses of 3 to 26 solar masses that trend with but are not fully set by CO core mass.
MOFAT applied to SN2024ggi shows CO triggering inner SiO formation with a receding edge, order-of-magnitude mass drop, clumping signatures, and no dust formation.
For a low-mass CCSN progenitor, rotation alone weakly and non-monotonically affects explosion energy and observables; only the fastest spin yields T/|W| spiral modes and spin-kick alignment, with core spin amplified by ~4000.
A minimalist analytic extension shows spin-kick alignment in the tug-boat mechanism arises either from fast rotation averaging out perpendicular asymmetries or from spin-aligned mass flux, but the former requires unrealistically high rotation unless magnetic angular-momentum transport is efficient.
cWB XP on LIGO O3/O4 data yields near-perfect SASI identification from GWs alone at O4 sensitivity (PD=0.97 at 10 kpc for PFI=0.01) and improves joint O3 detection over prior work.
