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…
FAST drift scan survey for HI intensity mapping: simulation on hunting HI filament with pairwise stacking
Diyang Liu, Yichao Li, Denis Tramonte +5
Filaments stand as pivotal structures within the cosmic web. However, direct detection of the cold gas content of the filaments remains challenging due to its inherent low brightne…
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…
Searching for axion dark matter gegenschein of the Vela supernova remnant with FAST
Wenxiu Yang, Yitian Sun, Yougang Wang +7
Axions are one of the leading dark matter candidates. If we are embedded in a Milky Way dark matter halo comprised of axions, their stimulated decay would enable us to observe a co…
