Gaussian-process reconstructions and model building of quintom dark energy from latest cosmological observations
Yuhang Yang, Qingqing Wang, Chunyu Li +4
In this article we use the latest cosmological observations, including SNe, BAO, CC and RSD, to reconstruct the cosmological evolution via the Gaussian process. At the background l…
