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…
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 $…
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…
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…
