Influence of the correlation prior on reconstruction of the dark energy equation of state

31 Jul 2019Youhua XuHu ZhanYeuk-Kwan Edna Cheung

Non-parametric reconstruction of the dark energy equation of state (EoS) aims to determine the EoS as a function of redshift without invoking any particular dark energy model, so that the resulting EoS can be free of model-induced biases or artifacts. Without proper regularization, however, such reconstruction is often overwhelmed by the noise of poorly constrained modes... (read more)
