SUMMARY:The Theory of Three-Dimensional Core-Collapse Supernova Explos
 ions\, Physics Department Colloquium\, Adam Burrows\, Princeton Univer
 sity
DESCRIPTION:Using our code Fornax we have simulated the collapse and e
 xplosion of the <br>
\ncores of many massive-star models in three spat
 ial dimensions. This is the <br>
\nmost comprehensive set of realistic
  3D core-collapse supernova (CCSN) <br>
\nsimulations yet performed an
 d has provided very important insights into <br>
\nthe mechanism and c
 haracter of this 60-year-old astrophysical puzzle. Most <br>
\n3D mode
 ls explode naturally and without artifice by the neutrino <br>
\nmecha
 nism\, aided by turbulent convection.  I will present detailed results
  <br>
\nfrom this suite of runs and the novel conclusions derived from
  our new <br>
\ncapacity to simulate many 3D\, as opposed to 2D and 1D
 \, full physics models <br>
\nevery year. Emerging are insights into t
 he criteria for explosion\, the <br>
\nsystematics of explosion energy
  and residual neutron-star mass with <br>
\nprogenitor\, the character
 istics of proto-neutron star convection\, neutrino <br>
\nand gravitat
 ional-wave emissions and signatures\, the morphology of CCSN <br>
\nex
 plosions\, and supernova nucleosynthesis.  This new capability\, enabl
 ed <br>
\nby this new algorithm and modern HPC assets\, is poised to t
 ransform our <br>
\nunderstanding of this central astrophysical phenom
 enon.<br>
