Stages of Reionization as revealed by the Minkowski Functionals
Zhaoting Chen, Yidong Xu, Yougang Wang +1
We study the evolution of the hydrogen ionization field during the epoch of reionization (EoR) using semi-numerical simulations. By calculating the Minkowski functionals (MFs) of t…
Cosmology with Phase 1 of the Square Kilometre Array; Red Book 2018: Technical specifications and performance forecasts
Square Kilometre Array Cosmology Science Working Group, David J. Bacon, Richard A. Battye +44
We present a detailed overview of the cosmological surveys that will be carried out with Phase 1 of the Square Kilometre Array (SKA1), and the science that they will enable. We hig…
Can Conformal and Disformal Couplings Between Dark Sectors Explain the EDGES 21cm Anomaly?
Linfeng Xiao, Rui An, Le Zhang +3
The recently announced result by EDGES points an unexpected excess in the 21 cm global brightness temperature from cosmic dawn at , potentially indicating new phenomena b…
Progress in the Construction and Testing of the Tianlai Radio Interferometers
Santanu Das, Christopher J. Anderson, Reza Ansari +44
The Tianlai Pathfinder is designed to demonstrate the feasibility of using a wide field of view radio interferometers to map the density of neutral hydrogen in the Universe after t…
The Global 21 cm Absorption from Cosmic Dawn with Inhomogeneous Gas Distribution
Yidong Xu, Bin Yue, Xuelei Chen
We make an analytical estimate of the maximum 21 cm absorption signal from the cosmic dawn, taking into account the inhomogeneity of gas distribution in the intergalactic medium (I…
An imaging algorithm for a lunar orbit interferometer array
Qizhi Huang, Shijie Sun, Shifan Zuo +5
Radio astronomical observation below 30 MHz is hampered by the refraction and absorption of the ionosphere, and the radio frequency interference (RFI), so far high angular resoluti…
The Neutral Islands during the Late Epoch of Reionization
Yidong Xu, Bin Yue, Xuelei Chen
The large-scale structure of the ionization field during the epoch of reionization (EoR) can be modeled by the excursion set theory. While the growth of ionized regions during the…
