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…
Eleven Local Volume dwarf galaxies in the FASHI survey
Aleksandra Nazarova, Dmitry Makarov, Igor Karachentsev +2
We determined HI parameters for eleven nearby late-type dwarf galaxies using FASHI data cubes, despite the fact that the first version of the FASHI catalog does not list any radio…
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…
FAST Reveals the Extended HI Halo and Accretion Signatures of NGC2683
Qian Jiao, Ming Zhu, Bernd Vollmer +5
We present the results of our recent HI observations conducted on the edge-on galaxy NGC2683 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). In comparison t…
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…
