Null test for cosmic curvature using Gaussian process
Peng-Ju Wu, Jing-Zhao Qi, Xin Zhang
The cosmic curvature , which determines the spatial geometry of the universe, is an important parameter in modern cosmology. Any deviation from would have a pr…
A path to precision cosmology: synergy between four promising late-universe cosmological probes
Peng-Ju Wu, Yue Shao, Shang-Jie Jin +1
In the next decades, it is necessary to forge new late-universe cosmological probes to precisely constrain the Hubble constant and the equation of state of dark energy simultaneous…
Effects of Small-Scale Absorption Systems on Neutral Islands during the Late Epoch of Reionization
Peng-Ju Wu, Yidong Xu, Xin Zhang +1
The reionization process is expected to be prolonged by the small-scale absorbers (SSAs) of ionizing photons, which have been seen as Lyman-limit systems in quasar absorption line…
Prospects for measuring dark energy with 21 cm intensity mapping experiments
Peng-Ju Wu, Xin Zhang
Using the 21 cm intensity mapping (IM) technique can efficiently perform large-scale neutral hydrogen surveys, and this method has great potential for measuring dark-energy paramet…
Cosmological parameter measurement and neutral hydrogen 21 cm sky survey with the Square Kilometre Array
Yidong Xu, Xin Zhang
In order to precisely measure the cosmological parameters and answer the fundamental questions in cosmology, it is necessary to develop new, powerful cosmological probes, in additi…
