TL;DR: In this article, the authors studied the early evolution of a "normal" SN Ia, its compositional structure, and its elusive progenitor system using high signal-to-noise spectra.
Journal ArticleDOI
A review of type Ia supernova spectra
TL;DR: In this article, the authors discuss a necessary next step toward consistently modeling and directly measuring spectroscopic observables of type Ia supernova spectra, which will be relevant even after progenitors are observed and detailed models are refined.

TL;DR: This is the first time a Burst Buffer has been stressed at scale by diverse, real user workloads and therefore these lessons will be of considerable benefit to shaping the developing use of Burst Buffers at HPC centers.
