Ages of Giant Elliptical Galaxies as Evidence for the Cosmological Constant
Published online by Cambridge University Press: 25 May 2016
Abstract
There is a compelling evidence for old ages of giant elliptical galaxies, about 3 Gyrs older than our Galaxy, from space ultraviolet observations and new population synthesis models. Alternative interpretation requires ad-hoc assumptions yet it produces poor fitting to observational data. If confirmed by future space UV mission, this would provide evidence for non-zero cosmological constant from time scale test.
