Prospects for cosmological research using hundred-meter-class radio telescopes: 21-cm intensity mapping survey strategies with QTT, JRT, and HRT
Jun-Da Pan, Yichao Li, Guo-Hong Du +2
Understanding dark energy requires precision measurements of the expansion history of the universe and the growth of large-scale structure. The 21 cm intensity mapping (21 cm IM) t…
Exploring HI Galaxy Redshift Survey Strategies for the FAST Core Array Interferometry
Zhenglong Li, Diyang Liu, Chengliang Xu +2
We explore the feasibility of HI galaxy redshift surveys with the Five-hundred-meter Aperture Spherical Telescope (FAST) and its proposed Core Array interferometry. Using semi-anal…
FAST drift scan survey for HI intensity mapping: simulation on Bayesian-stacking-based HI mass function estimation
Jiaxin Wang, Yichao Li, Hengxing Pan +7
This study investigates the estimation of the neutral hydrogen (HI) mass function (HIMF) using a Bayesian stacking approach with simulated data for the Five-hundred-meter Aperture…
The Three Hundred Project: The relationship between the shock and splashback radii of simulated galaxy clusters
M. Zhang, K. Walker, A. Sullivan +4
Observations of the intracluster medium (ICM) in the outskirts of galaxy clusters reveal shocks associated with gas accretion from the cosmic web. Previous work based on non-radiat…
Extracting the Epoch of Reionization Signal with 3D U-Net Neural Networks Using Data-driven Systematic Effect Model
Li-Yang Gao, Léon V. E. Koopmans, Florent G. Mertens +11
Neutral hydrogen (HI) serves as a crucial probe for the Cosmic Dawn and the Epoch of Reionization (EoR). Actual observations of the 21-cm signal often encounter challenges such as…
FAST Drift Scan Survey for HI Intensity Mapping. II. Stacking-based Beam Construction of the 19-feed Array at GHz
Xinyang Zhao, Yichao Li, Wenxiu Yang +7
Neutral hydrogen (HI) intensity mapping (IM) presents great promise for future cosmological large-scale structure surveys. However, a major challenge for HIIM cosmological studies…
