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…
The FAST All Sky HI Survey DR2: the FASHI Catalog and the HI Mass Function
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 $…
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…
Deep neutral hydrogen observations of the early-type galaxy NGC 2768: collided by a newly discovered satellite galaxy?
Nai-Ping Yu, Ming Zhu, Jin-Long Xu +3
We present the results of a deep neutral hydrogen (Hi) observation of the early-type galaxy NGC 2768 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). Leverag…
Discovery of a high-velocity cloud of the Milky Way as a potential dark galaxy
Xiao-Lan Liu, Jin-Long Xu, Peng Jiang +6
High-velocity clouds (HVCs) are composed of neutral hydrogen (HI) moving at velocities that deviate from the general rotational motion of the Milky Way. Currently, the origins of t…
