The FAST HI 21-cm Absorption Blind Survey. III. OH Absorption Search in the 21-cm Absorber Sample and Continued HI Absorption Search

Wenkai Hu, Yougang Wang, Jeremy Darling +11

We present the first blind search for OH 18-cm absorption with the Five-hundred-meter Aperture Spherical Telescope (FAST), conducted alongside the HI 21-cm absorption search. Our p…

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…

Environmental effects on satellite galaxies from the perspective of cold gas

Hongxing Chen, Lizhi Xie, Jie Wang +4

Environment plays a pivotal role in shaping the evolution of satellite galaxies. Analyzing the properties related to the cold gas phase of satellites provides insights into unravel…

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…

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…
