1/f Noise Analysis for FAST HI Intensity Mapping Drift-Scan Experiment
Wenkai Hu, Yichao Li, Yougang Wang +8
We investigate the 1/f noise of the Five-hundred-meter Aperture Spherical Telescope (FAST) receiver system using drift-scan data from an intensity mapping pilot survey. All the 19…
The Atomic Hydrogen Content of Galaxies as a function of Group-Centric Radius
Wenkai Hu, Luca Cortese, Lister Staveley-Smith +5
We apply a spectral stacking technique to Westerbork Synthesis Radio Telescope observations to measure the neutral atomic hydrogen content (HI) of nearby galaxies in and around gal…
The cosmic atomic hydrogen mass density as a function of mass and galaxy hierarchy from spectral stacking
Wenkai Hu, Barbara Catinella, Luca Cortese +5
We use spectral stacking to measure the contribution of galaxies of different masses and in different hierarchies to the cosmic atomic hydrogen (HI) mass density in the local Unive…
Forecast for FAST: from Galaxies Survey to Intensity Mapping
Wenkai Hu, Xin Wang, Fengquan Wu +3
The Five-Hundred-Meter Aperture Spherical Radio Telescope(FAST) is the largest single-dish radio telescope in the world. In this paper, we make forecast on the FAST HI large scale…
An accurate low-redshift measurement of the cosmic neutral hydrogen density
Wenkai Hu, Laura Hoppmann, Lister Staveley-Smith +7
Using a spectral stacking technique, we measure the neutral hydrogen (HI) properties of a sample of galaxies at across 35 pointings of the Westerbork Synthesis Radio Tel…
