FASHI DR2: A Catalog of 132 Low-Redshift HI 21 cm Absorption Systems
Chuan-Peng Zhang, Ming Zhu, Peng Jiang +7
We present an untargeted survey of 21 cm HI absorption systems based on the second data release of the FAST All Sky HI survey (FASHI DR2), covering approximately 19,500 deg a…
A Catalog of Compact High-Velocity Clouds from the FAST All-Sky HI Survey (FASHI) DR2
Jin-Long Xu, Chuan-Peng Zhang, Xiao-Lan Liu +3
The paper presents a catalog of 192 compact high‑velocity clouds identified in the FAST All‑Sky HI Survey, most of which are concentrated around the Andromeda galaxy and are likely…

Chuan-Peng Zhang, Ming Zhu, Peng Jiang +8
The FAST All Sky HI Survey (FASHI) conducted with the Five-hundred-meter Aperture Spherical radio Telescope (FAST) has mapped of the sky north of DEC $…
From emission to absorption: the FAST observation of the OH 18-cm lines from the Comet C2025/A6
Dongyue Jiang, Lei Qian, Minglei Guo +14
We observed comet C/2025 A6 with the Five-hundred-meter Aperture Spherical radio Telescope (FAST) equipped with the ultra-wideband receiver from 2025 October 23 to November 8, and…
Unveiling a Thin Filament of the Cosmic Web in the Ursa Major Supergroup
Jin-Long Xu, Ming Zhu, Peng Jiang +6
Filaments are crucial components of the cosmic web, representing the extensive and aligned distributions of galaxies and gas. Using the Five-hundred-meter Aperture Spherical radio…
Gas Accretion from a Neighbouring Galaxy Fuels the Low-luminosity AGN in NGC 4278
Jin-Long Xu, Nai-Ping Yu, Ming Zhu +4
How a seemingly `dead' host galaxy provides fuel for its active galactic nuclei (AGN) remains an unresolved problem. Using the Five-hundred-meter Aperture Spherical radio Telescope…
