Query: Possible indications for jittering jets in core collapse supernova
  explosion simulations   I analyse recent three-dimensional hydrodynamical simulations of exploding
core collapse supernovae (CCSNe) and find that a rapid increase in the
diagnostic explosion energy occurs parallel to, or very shortly after, the
accretion of gas with relatively large amount of angular momentum and/or
specific angular momentum. The tendency towards a positive correlation between
angular momentum accretion and the increase in the explosion energy appears
despite the absence of magnetic fields in the simulations. I speculate that the
inclusion of magnetic fields would make this positive correlation much stronger
and would increase the explosion energy. At times, the high angular momentum
accretion leads to a bipolar outflow that in some cases changes directions. I
argue that there is a mutual influence between neutrino heating and stochastic
angular momentum, and that both operate together to explode the star with
bipolar outflows that change directions, namely, jittering jets. This study
calls for a deep flow analysis of simulations of CCSNe, e.g., to present the
flow structure, the density, and the angular momentum of the flow near the
newly born neutron star (NS).
