PUSHing core-collapse simulations to explosion

We report on the PUSH method for artificially triggering core-collapse supernova explosions of massive stars in spherical symmetry. The PUSH method increases the energy deposition in the gain region proportionally to the heavy flavor neutrino fluxes.We summarize the parameter dependence of the method and calibrate PUSH to reproduce SN 1987A observables. We identify a best-fit progenitor and set of parameters that fit the explosion properties of SN 1987A, assuming 0.1 M-circle dot of fallback. For the explored progenitor range of 18-21 M-circle dot, we find correlations between explosion properties and the compactness of the progenitor model
