Dark Energy and Open universe

A study on Dark Energy taken as a possible dynamic energy in 2012 in China, indicates as such it could be found 'a distinct open universe', writes its authors, Jing-Fei Zhang, Yun-He Li and Xin Zhang. They have been on a multiyear trial for non-flat universe models. This result is in brazen "first" contrast with more conservative speculations in cosmology that are feign to admit an open universe

This particular model is the NADE (new agegraphic dark energy), from studies of the WMAP7 seven year data.

The team collaborated from Northeastern University at Shenyang, China and Center for High Energy Physics, Peking University, Beijing, China. See arxiv.org 1212.0300.

They say that in previous studies with morphology of the universe that spatial curvature is usually not factored in for calculations. Another workup can be found: arxiv.org 1402.4522. There is an earlier work in Physical Review D, 58 by J.D. Cohn and D.I. Kaiser of 1988 showing similar line of pursuit toward an open universe. "Rather, it is important to understand the dynamics of these modes within region R, corresponding to our observable, open universe." "These non-Cauchy surfaces (fixed time in the flat coordinates) extend into the open universe." Their paper titled, "Where do all the Supercurvatures modes go?"

The current team indicated with their treatment, that dark energy could be figured without going  w=-1 crossing and so gravity insufficiency does not occur. The NADE is to have pressureless matter
