I will present recent 3D core-collapse supernova and multimessenger work from the Stockholm Supernova theory group. These simulations include: (a) magnetohydrodynamic simulations of a high compact progenitor, touching upon the explosion mechanism of rapidly rotating, magnetized core collapse events and particularly on the impact of rotation and magnetic fields; (b) the core-collapse, and long term evolution of a low-metallicity, low-mass, commonly-explored progenitor allowing a comparison among simulation groups; and (c) a preliminary look at a larger set of simulations spanning progenitor mass using a more approximate neutrino treatment and (d) a sneak peak at several cases of precollapse, Multidimensional evolution in 3D. Collectively these simulations span a broad range of the progenitor population and highlight the growing diversity of outcomes from core collapse, including neutron stars, magnetars, as well as simultaneous explosions and black hole formation.
