TL;DR: The Supernova Acceleration Probe (SNAP) as discussed by the authors uses Type Ia supernovae (SNe Ia) as distance indicators to measure the effect of dark energy on the expansion history of the universe.

Type Ia SNe along redshift: the R(Si II) ratio and the expansion velocities in intermediate z supernovae
G. Altavilla,P. Ruiz-Lapuente,A. Balastegui,Javier Méndez,Michael G. Irwin,Cristina España-Bonet,K. Schamaneche,C. Balland,Richard S. Ellis,Sebastien Fabbro,G. Folatelli,A. Goobar,Wolfgang Hillebrandt,R. M. McMahon,M. Mouchet,A. Mourao,S. Nobili,R. Pain,Vallery Stanishev,Nicholas A. Walton +19 more
TL;DR: In this article, the authors studied intermediate-z SNe Ia using the empirical physical diagrams which enable to learn about those SNe explosions and showed that the expansion velocities of Ca II and Si II are similar to the nearby counterparts.

TL;DR: This corrects the article to show that the method used to derive the H2O2 “spatially aggregating force” is based on a two-step process, not a single step, like in the previous version of this paper.
