SUMMARY:The Rugged Landscape of Core-Collapse Supernova Explosions
DESCRIPTION:The Rugged Landscape of Core-Collapse Supernova Explosions\nDr.
  Ondrej Pejcha\n\nThe collapse of the core and the associated supernova ex
 plosion mark the  end of life of most massive stars, but the mechanism of 
 explosion is  poorly understood and perhaps even unknown. Some of its puzz
 ling  features were recently observed in the statistics of supernova  prog
 enitors, explosion energies, nickel yields, and in the remnant  neutron st
 ar and black hole mass functions. I will describe my  theoretical studies 
 of the supernova explosion mechanism, its dependence  on the progenitor st
 ar structure, and the connection with observables. I  will argue that succ
 essful explosions are intertwined with failures in a  complex but well-def
 ined pattern that is tied to the pre-collapse  structure of the progenitor
  star. I will also present a new method to  extract the supernova paramete
 rs from light curves and expansion  velocities, and illustrate how to cons
 train the explosion mechanism in  the future.
