Imaging sensitivity of a linear interferometer array on lunar orbit
Yuan Shi, Yidong Xu, Li Deng +6
Ground-based observation at frequencies below 30 MHz is hindered by the ionosphere of the Earth and radio frequency interference. To map the sky at these low frequencies, we have p…
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…
An Ultra-long Wavelength Sky Model with Absorption Effect
Yanping Cong, Bin Yue, Yidong Xu +3
The radio sky at frequencies below MHz is still largely unknown, this remains the last unexplored part of the electromagnetic spectrum in astronomy. The upcoming space exp…
Maximum Absorption of the Global 21 cm Spectrum in the Standard Cosmological Model
Yidong Xu, Bin Yue, Xuelei Chen
The absorption feature in the global spectrum is likely the first 21 cm observable from the cosmic dawn, which provides valuable insights into the earliest history of structure for…
Prospects for Constraining Interacting Dark Energy Models with 21 cm Intensity Mapping Experiments
Ming Zhang, Bo Wang, Peng-Ju Wu +4
We forecast constraints on cosmological parameters in the interacting dark energy models using the mock data generated for neutral hydrogen intensity mapping (IM) experiments. In t…
