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…
First Submillimeter Lights from Dome A: Tracing the Carbon Cycle in the Feedback of Massive Stars
Yan Gong, Jiaqiang Zhong, Yuan Ren +38
The cycling of carbon between its ionized, atomic, and molecular phases shapes the chemical compositions and physical conditions of the interstellar medium (ISM). However, ground-b…
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…
FAST Discovery of A Gas-rich and Ultra-faint Dwarf Galaxy: KK153
Jin-Long Xu, Ming Zhu, Nai-Ping Yu +4
Based on a high-sensitivity HI survey using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we identified an isolated HI cloud with a system velocity of ~127.0 km…
