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 hunting HI filament with pairwise stacking
Diyang Liu, Yichao Li, Denis Tramonte +5
Filaments stand as pivotal structures within the cosmic web. However, direct detection of the cold gas content of the filaments remains challenging due to its inherent low brightne…

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…
