The Emerging Picture of Supernova Remnants and GRBs at High Energies

In the last two years, high-energy studies of supernova remnants (SNRs) and gamma-ray bursts (GRBs) have yielded many new insights regarding the nature of explosions and their environments. In this talk, I will highlight several recent advances in these fields catalyzed by high energy theory and observations, with emphasis on progenitor systems, nucleosynthesis, and particle acceleration. Finally, I will discuss anticipated advances with upcoming facilities, like Astro-H and Advanced LIGO.
