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…
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.…
A Morphological Identification and Study of Radio Galaxies from LoTSS DR2. III. The Multiwavelength Analysis of Winged Radio Galaxies
Soumen Kumar Bera, Taotao Fang, Magdalena Kunert-Bajraszewska +5
We present a multiwavelength follow-up study of 621 winged radio galaxies (WRGs) recently identified from LoTSS DR2, constituting the largest statistically significant samples of X…
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…
