Electron Densities of Typical Low-Mass Galaxies at z~2-7 from Stacked JWST/NIRSpec Spectra
Shihong Liu, Yu Rong
Direct electron-density measurements at high redshift are usually limited to galaxies with individually strong density-sensitive doublets, and therefore may not trace the average i…
Stellar Surface Density Modulates MgII Cool-gas Outflow Absorption in DESI Star-forming Galaxies
Yu Rong, Shihong Liu
Galaxy outflows are usually ordered by stellar mass and star-formation rate (SFR), but the same feedback budget may couple differently to gas in diffuse and compact galaxies. We us…
Halo Spin Depends on The Distance to Cosmic Filament
Shihong Liu, Yu Rong
We employ a semi-analytical methodology to estimate the dark matter halo spin of HI-rich galaxies in the Arecibo Legacy Fast Alfa Survey and investigate the relationship between ha…
Quantifying the Relationship Between Galaxy Specific Star Formation Rate And Halo Spin For Star-forming Galaxies
Wenxiao Xue, Zichen Hua, Yu Rong
Utilizing ALFALFA HI data, we investigate the relationship between specific star formation rate (sSFR) and halo spin across various star-forming galaxies. Our analysis reveals weak…
Strong Correlation between Galactic HI-to-stellar Mass Ratio And Halo Spin Explored by HI-rich Galaxies
Shihong Liu, Yu Rong, Zichen Hua +1
Using a semi-analytic approach, we estimate halo spins for a large sample of HI-rich galaxies from the Arecibo Legacy Fast Alfa Survey and examine the correlation between HI mass f…
The baryonic Tully-Fisher relation of HI-bearing low-surface brightness galaxies implies their formation mechanism
Zichen Hua, Yu Rong, Hui-jie Hu
We investigate the baryonic Tully-Fisher relation in low surface brightness galaxies selected from the Arecibo Legacy Fast ALFA survey. We find that the -bearing low surfac…
