Supernova explosions terminate the lives of massive stars, produce
and disseminate a major fraction of the heavy elements, play an
important role as neutrino and particle laboratories, and give birth
to neutron stars and stellar-mass black holes, which have recently
become sources of measured gravitational waves. After more than
50 years of progressively improved computational modeling,
first-principle three-dimensional (3D) hydrodynamic simulations with
detailed neutrino physics have meanwhile accomplished to demonstrate
the viability of the neutrino-driven explosion mechanism. The
consequences of such explosions can now be confronted with observations.
In particular, self-consistent 3D simulations can provide new insights
into the geometrical and chemical structure of young supernova remnants,
possible explosion-progenitor connections, and the natal properties
(masses, kicks, spins) of the compact objects formed in stellar
core-collapse events. They have also allowed us to better understand
the nature of the progenitor and the explosion of the famous
Supernova 1987A and to predict the most-likely location of its relic
neutron star.
