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…
Insights into the Physical Nature of Polar Ring Galaxies from H I Observations
Niankun Yu, Han Zheng, Chao-Wei Tsai +10
Polar ring galaxies (PRGs) host an outer ring of gas and stars oriented nearly perpendicular to the main stellar body. They represent extreme examples of misaligned systems and pro…
Dark matter in ALFALFA galaxies: Investigating galaxy-halo connection
Meng Yang, Ling Zhu, Niankun Yu +4
This paper aims to investigate the galaxy-halo connection using a large sample of individual galaxies with integrated spectra. We determine their dark matter conten…
Investigating the Impacts of AGN Activities on Dwarf Galaxies with FAST HI Observations
Hong-Ying Chen, Chao-Wei Tsai, Pei Zuo +9
We present the results of Hi line observations towards 26 Active Galactic Nuclei (AGN)-hosting and one star-forming dwarf galaxies (Mstar < 10^9.5 Msun) with the 19-beam spectral l…
Deep Andromeda JCMT-SCUBA2 Observations. The Submillimeter Maps and Giant Molecular Clouds
Sihan Jiao, Jingwen Wu, Hauyu Baobab Liu +23
We have carried out unprecedentedly deep, nearly confusion-limited JCMT-SCUBA2 mapping observations on the nearest spiral galaxy, M31 (Andromeda). The 850 m image with a …
Linking Electron Density with Elevated Star Formation Activity from to
Sijia Li, Si-Yue Yu, Luis C. Ho +7
The interstellar medium (ISM) in high-redshift galaxies exhibits significantly higher electron densities () than in the local universe. To investigate the origin of this…
