Journal ArticleDOI
Superacceleration as the signature of a dark sector interaction
TL;DR: In this paper, the authors show that an interaction between dark matter and dark energy generically results in an effective dark energy equation of state of w <-1, which is consistent with all current observations, the tightest constraint coming from estimates of the matter density at different redshifts.
Journal ArticleDOI
Weighing neutrinos with galaxy cluster surveys.
TL;DR: It is shown that a weak lensing selected sample of > or approximately 100,000 clusters could tighten the current upper bound on the sum of masses of neutrino species by an order of magnitude, to a level of 0.03 eV.
