Abstract: The relevance of the standing accretion shock instability (SASI) compared to neutrino-driven convection in three-dimensional (3D) supernova-core environments is still highly controversial. Studying a 27 M ⊙ progenitor, we demonstrate, for the first time, that violent SASI activity can develop in 3D simulations with detailed neutrino transport despite the presence of convection. This result was obtained with the Prometheus-Vertex code with the same sophisticated neutrino treatment so far used only in 1D and 2D … Show more

“…Further important improvements in numerical realism include removing the restriction of axial symmetry and moving to 3D, as has been initiated by Hanke et al (2013) using VERTEX, Lentz et al (2015) using CHIMERA, and Takiwaki et al (2012Takiwaki et al ( , 2014 using Zeus+IDSA,performing these simulations in full general relativity rather than hybrid approximations,employing multidimensional transport instead of RbR,and better approximations to Boltzmann transport. Resolution studies need to be performed in order to assure numerical convergence.…”

“…Three-dimensional simulations with spectral, RbR neutrino transport, approximate general relativity, and state-of-the-art weak interactions are underway, and the results from early stages of the post-bounce dynamics have been reported by Hanke et al (2013), using VERTEX, and Lentz et al (2015), using CHIMERA. Takiwaki et al (2012Takiwaki et al ( , 2014 also report 3D Newtonian simulations using Zeus +IDSA.…”

“…We draw from Woosley et al (2002) the progenitor model s27, which has been studied in a number of previous works (e.g., Müller et al 2012a;Hanke et al 2013;Ott et al 2013;Couch & O'Connor 2014;Abdikamalov et al 2015). In all simulations, we employ the = K 220 MeV 0 variant of the equation of state of Lattimer & Swesty (1991) .…”

“…Multiple simulations including energydependent (multi-group) neutrino transport and imposing axial symmetry (2D) do exhibit explosions (Müller et al 2012b(Müller et al , 2012aBruenn et al 2013Bruenn et al , 2016, although some do not . Interestingly, the first simulations including ray-by-ray neutrino transport 11 without symmetries imposed three-dimensionally on the hydrodynamics did not find explosions in models that exploded when axisymmetry was assumed (Hanke et al 2013). Melson et al (2015) showed that in three-dimensional (3D) simulations that are close to the threshold of explosion, modified neutrino interaction physics can facilitate explosion.…”

“…In a conformally flat ray-by-ray approximation, Müller et al [29] developed a scheme that renders non-conservative (in a sense discussed in Ref. [30]) energy and momentum equations consistent with a conservative number equation, and have deployed it in 3D position space simulations retaining energy dependence [31]. (Another energy-dependent ray-by-ray simulation in 3D position space has been performed with a different approach, the 'isotropic diffusion source approximation' [32].)…”
