TL;DR: The most distant spectroscopically confirmed supernova was reported in this paper, and it was found to be similar to nearby type Ia supernovae, which suggests that we may live in a low-mass-density universe.

TL;DR: In this article, the authors used a light-curve width-corrected magnitudes as a function of redshift of distant (z = 0.35-0.46) supernovae to obtain a global measurement of the mass density.
