Identification and Study of Irregular Radio Sources with SKA Continuum Surveys
Tapan K. Sasmal, Xuelei Chen, Baoqiang Lao +5
Radio galaxies show a wide range of morphologies, from regular double-lobed systems to more complex and distorted radio structures. In this chapter, we focus on irregular radio mor…
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…
A Statistical Study of HI Gas in AGN-Hosting and Satellite Galaxies from ALFALFA and FASHI
Shuanghao Shu, Wenkai Hu, Junqiang Ge +6
We investigate the relative importance of Active Galactic Nucleus (AGN) feedback and environmental processes using a large sample of HI galaxies from the ALFALFA and FASHI surveys.…
Cross-Comparison of Galaxies Detected in the CSST Spectroscopic Survey and the SKA HI Survey
Yingfeng Liu, Furen Deng, Wenxiang Pei +8
We present a forward-modeling framework to forecast the galaxies detected in the Chinese Space Station Survey Telescope (CSST) spectroscopic survey and the Square Kilometre Array (…
The Quenching Mechanisms of Field Dwarf Galaxies
Zuoyu Wu, Yougang Wang, Shihong Liao
Isolated dwarf galaxies are intrinsically faint and difficult to detect. The limited sample size makes it challenging to observationally constrain the physical mechanisms that quen…
FATHOMER survey: III. Preliminary HI galaxy identification results
Shuanghao Shu, Yichao Li, Wenxiu Yang +6
We present the HI galaxy observation results of the FATHOMER (FAst neuTral HydrOgen intensity Mapping ExpeRiment), a pilot drift scan survey by the Five-hundred-meter Aperture Sphe…
A Multi-Mechanism Hybrid Model of Peaked-Spectrum Radio Sources
Guang-Chen Sun, Yichao Li, Furen Deng +6
The peaked-spectrum (PS) sources exhibit turnover characteristics in their broad radio spectra. However, the mechanism underlying this phenomenon remains elusive. The two most comm…
Dynamical Models of the Milky Way in Action Space with LAMOST DR8 and GAIA EDR3
Guang-Chen Sun, Qiao Wang, Shude Mao +6
This work explores dynamical models of the Milky Way (MW) by analyzing a sample of 86,109 K giant stars selected through cross-matching the LAMOST DR8 and Gaia EDR3 surveys. Our ea…
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…
Observation of HI around three satellite galaxies of the M31 with the FAST: Andromeda II, NGC 205, and NGC 185
Ziming Liu, Jie Wang, Yingjie Jing +6
With the exceptional sensitivity of the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we conducted observations of the neutral hydrogen (HI) in the circumgalactic m…
