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…
What is the True HI Gas Content in Massive Quiescent Galaxies in the Local Universe?
Xiao Li, Cheng Li, Cheng Cheng +3
While massive quiescent galaxies are known to be poor in atomic hydrogen (HI), their true HI content remains poorly constrained due to the limited sensitivity and morphological bia…
What drives the HI content of central galaxies -- A comparison between hydrodynamic simulations and observations using Random Forest
Xiao Li, Cheng Li, Houjun Mo
We investigate the driving mechanisms for the HI gas content in star-forming central galaxies at low redshift, by examining the HI-to-stelalr mass ratio () in bo…
On the existence, rareness and uniqueness of quenched HI-rich galaxies in the local Universe
Xiao Li, Cheng Li, H. J. Mo +3
Using data from ALFALFA, xGASS, HI-MaNGA and the Sloan Digital Sky Survey (SDSS), we identify a sample of 47 "red but HI-rich"(RR) galaxies with and unusually high HI-t…
