Megaparsec-Scale Neutral Hydrogen Flows in the Neighborhood of Hickson Compact Group 100
Qingzheng Yu, Taotao Fang, Enrico M. Di Teodoro +2
The evolution of galaxies is strongly influenced by their ability to exchange gas with their surroundings, yet direct observational constraints on these processes remain scarce. Us…
Probing the Hot Gaseous Halos of Milky Way-like Galaxies in the TNG50 simulation
Zhijie Zhang, Xiaoxia Zhang, Taotao Fang +9
The origin and structure of the hot (K) gaseous halo around Milky Way (MW)-mass galaxies provide a critical test for galaxy formation models. We perform a comprehensi…
HI Gas and Star Formation in Major Galaxy Pairs from the FAST All-Sky HI Survey (FASHI)
Shulan Yan, Qingzheng Yu, Taotao Fang +6
Atomic hydrogen (HI) plays a fundamental role in fueling star formation in galaxies. However, the behavior of HI gas in interacting systems, particularly galaxy pairs, remains elus…
A FAST Survey of H I Absorption in Low-power Radio Sources
Yang Su, Qingzheng Yu, Taotao Fang +3
We conducted a HI 21cm absorption study of a sample of 147 nearby (z < 0.1) low-power radio sources with and $\log(P_{…
HI Content of Group Galaxies from the FAST All Sky HI Survey
Shulan Yan, Andrew Ma, Qingzheng Yu +3
We investigate the atomic gas (HI) content of galaxies in groups using early data from the FAST All Sky HI survey (FASHI). Taking advantage of FAST's blind, wide-area coverage and…
Tracing the Origins of Hot Halo Gas in Milky Way-Type Galaxies with SMUGGLE
Zhijie Zhang, Xiaoxia Zhang, Hui Li +8
Current galaxy formation models predict the existence of X-ray-emitting gaseous halos around Milky Way (MW)-type galaxies. To investigate properties of this coronal gas in MW-like…
