Beyond : Observational Constraints on Almost-CDM Cosmologies
Jess Worsley, Saikat Chakraborty, Peter Dunsby
The cosmographic condition provides the kinematical signature of the spatially flat CDM model independently of any specific dark-energy or modified-gravity theory. We…

A model independent approach to the study of structure growth in gravity
Kelly MacDevette, Jess Worsley, Peter Dunsby +1
Over the last decade, much attention has been given to the study of modified gravity theories to find a more natural explanation for the late-time acceleration of the Universe. Par…
