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
The paper uses FAST and DESI data to stack HI spectra of galaxies in 36 nearby clusters, showing that neutral hydrogen content is already depleted out to five times the virial radi…
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 $…
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…
CRANE: Constrained Reasoning Injection for Code Agents via Nullspace Editing
Mingzhi Zhu, Michele Merler, Raju Pavuluri +1
Code agents must both reason over long-horizon repository state and obey strict tool-use protocols. In paired Instruct/Thinking checkpoints, these capabilities are complementary bu…
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…
