The 21-cm forest as a simultaneous probe of dark matter and cosmic heating history
Yue Shao, Yidong Xu, Yougang Wang +4
The absorption features in spectra of high-redshift background radio sources, caused by hyperfine structure lines of hydrogen atoms in the intervening structures, are known collect…
FAST drift scan survey for HI intensity mapping: I. preliminary data analysis
Yichao Li, Yougang Wang, Furen Deng +15
This work presents the initial results of the drift-scan observation for the neutral hydrogen (HI) intensity mapping survey with the Five-hundred-meter Aperture Spherical radio Tel…
Detections of 21-cm absorption with a blind FAST survey at z 0.09
Wenkai Hu, Yougang Wang, Yichao Li +10
We present the early science results from a blind search of the extragalactic HI 21-cm absorption lines at z 0.09 with the drift-scan observation of the Five-hundred-me…
Detecting HI Galaxies with Deep Neural Networks in the Presence of Radio Frequency Interference
Ruxi Liang, Furen Deng, Zepei Yang +9
In neutral hydrogen (HI) galaxy survey, a significant challenge is to identify and extract the HI galaxy signal from observational data contaminated by radio frequency interference…
