We present the first simulations of core-collapse supernovae (CCSNe) in axial
symmetry (2D) with feedback from fast neutrino flavor conversion (FFC). Our
schematic treatment of FFCs assumes instantaneous flavor equilibration under
the constraint of lepton-number conservation. Systematically varying the
spatial domain where FFCs are assumed to occur, we find that they facilitate SN
explosions in low-mass (9-12 solar masses) progenitors that otherwise explode
with longer time delays, whereas FFCs weaken the tendency to explode of
higher-mass (around 20 solar masses) progenitors.Comment: 7 pages, 4 figures, submitted to PR
