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…
An HI study of a large sample of ultra-diffuse galaxies
Ruilei Zhou, Ming Zhu, Chuan-Peng Zhang +5
By cross-matching the SMUDGes catalog with the FASHI and ALFALFA HI surveys, we construct an HI-detected sample of 112 ultra-diffuse galaxies (UDGs) and 48 low-surface-brightness (…
HI Depletion Begins Well Beyond the Virial Radius: A FAST Stacking Study of 36 Galaxy Clusters to 5R200
Cheng Cheng, Chuan-Peng Zhang, Edo Ibar +10
We present a stacking study of the neutral atomic hydrogen (HI) content in and around 36 local galaxy clusters at , using a combination of the FAST all sky HI survey (FASHI…
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
High-velocity clouds (HVCs) -- especially compact HVCs (CHVCs) -- are thought to serve as gaseous tracers of dark-matter-dominated subhalos, providing a crucial empirical link betw…
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 $…
The nature of Cloud-9: a compact core embedded in a diffuse envelope
Ruilei Zhou, Ming Zhu, Chuan-Peng Zhang +1
We present new HI observations of Cloud-9 with the Five-hundred-meter Aperture Spherical Telescope (FAST), measuringvtotal flux of 0.35 +- 0.03 Jy km/s. Combined with Very Large Ar…
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…
HiFAST: An HI data calibration and imaging pipeline for the FAST IV: The stray-radiation correction
Qingze Chen, Jie Wang, Yingjie Jing +12
Stray radiation is a considerable challenge for radio telescopes, requiring careful assessment due to its effects. This is crucial when the strong background flux from side lobes s…
A Spatially Resolved HI Survey of Seyfert Galaxies: the Role of AGN Feedback in Shaping Atomic Gas Reservoirs
Ruitian Li, Xin Wang, Daizhong Liu +19
Active galactic nucleus (AGN) feedback is a key ingredient in galaxy evolution, yet its impact on the cold atomic gas reservoir -- the neutral hydrogen (HI) phase -- remains poorly…
Optical identification of the FASHI sources: toward the extended Local Volume
Aleksandra E. Nazarova, Dmitry I. Makarov, Igor D. Karachentsev +3
We extracted a list of 662 nearby (within Mpc) HI-detection sources from the Five-hundred-meter Aperture Spherical radio Telescope (FAST) All Sky HI Survey (FASHI) and mad…
\HI 21-cm Line Properties of the Nearby LIRG IRAS 04296+2923
Guixiang Feng, Zhongzu Wu, Chuanpeng Zhang +1
We present an analysis of archival Very Large Array (VLA) and Five-hundred-meter Aperture Spherical radio Telescope (FAST) \HI\ 21 cm data, together with archival multi-band radio…
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…
