DESCRIPTION: Abstract:Supernovae and stellar collisions are the sometimes 
 incredibly luminous\, and sometimes not so luminous\, deaths of stars that
  play a vital role in chemical enrichment\, galaxy feedback mechanisms\, a
 nd our understanding of stellar evolution. Type Ia supernovae\, the explos
 ions of white dwarfs in binary systems\, are vital for constraining the co
 smological parameters. In this talk\, I will focus on the latest results o
 n the progenitors and explosion mechanisms of Type Ia supernovae from the 
 state-of-the-art transient survey\, the Zwicky Transient Facility\, and de
 scribe how their diversity may impact future precision measurements of dar
 k energy. I will also highlight recent advances in the related area of ste
 llar collisions\, which are testing the boundaries of current theoretical 
 models\, as well as discuss the link to kilonovae from neutron-star merger
 s (with and without associated gravitational-wave detections).
