Weak Evolution of Cosmic Atomic Hydrogen over the Past 4.5 Billion Years
Chuan-Peng Zhang, Hong Guo, Yizhou Gu +49
The cosmic star formation rate density (CSFRD) has declined sharply toward the present day, but the roles of the atomic and molecular gas reservoirs remain uncertain. We measure th…
HiFAST: An HI data calibration and imaging pipeline for the FAST IV: The stray-radiation correction
Qingze Chen, Jie Wang, Yingjie Jing +12
Stray radiation is a considerable challenge for radio telescopes, requiring careful assessment due to its effects. This is crucial when the strong background flux from side lobes s…
A Spatially Resolved HI Survey of Seyfert Galaxies: the Role of AGN Feedback in Shaping Atomic Gas Reservoirs
Ruitian Li, Xin Wang, Daizhong Liu +19
Active galactic nucleus (AGN) feedback is a key ingredient in galaxy evolution, yet its impact on the cold atomic gas reservoir -- the neutral hydrogen (HI) phase -- remains poorly…
Optical identification of the FASHI sources: toward the extended Local Volume
Aleksandra E. Nazarova, Dmitry I. Makarov, Igor D. Karachentsev +3
We extracted a list of 662 nearby (within Mpc) HI-detection sources from the Five-hundred-meter Aperture Spherical radio Telescope (FAST) All Sky HI Survey (FASHI) and mad…
