2. Constraining Dark Energy at high redshifts
- Title: The Hubble Space Telescope Cluster Supernova Survey. V. Improving the Dark-energy Constraints above z > 1 and Building an Early-type-hosted Supernova Sample
- Authors: N. Suzuki, D. Rubin, C. Lidman, et al.

Why it is important: Dark energy is still almost as mysterious as it was in its Nobel-prize winning discovery in 1998. These observations help tighten constraints on one of the things we most want to know– how does dark energy now compare to dark energy in the early universe?
