A RELHIC twin candidate near the galaxy M51
Qingze Chen, Jie Wang, Yingjie Jing +7
We report the discovery of a pair of H I clouds near M51 (NGC 5194) using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). These clouds have no optical counterpart…
The FAST Hundred-Deg HI Deep (HD) Survey: Early Results from the Pilot Survey
Chen Xu, Yingjie Jing, Jie Wang +26
The Hundred-deg HI Deep (HD) survey carried out with the Five-hundred-meter Aperture Spherical Telescope (FAST) is planned to map a contiguous region within the DESI DR1 fo…
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…
The FAST HI 21-cm absorption blind survey. II. -- Statistic Exploration for Associated and Intervening systems
Wenkai Hu, Yougang Wang, Yichao Li +12
We present an extragalactic HI 21-cm absorption lines catalog from a blind search at z 0.35, using drift-scan data collected in 1325.6 hours by the ongoing Commensal Ra…
