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…

Moderate Influence of Halo Spin on Stellar Mass Distributions in Dwarf and Massive Galaxies

Yu Rong, Zichen Hua, Huijie Hu

We estimate halo spins for HI-rich galaxies in the Arecibo Legacy Fast Alfa Survey using a semi-analytic approach, examining the relationship between halo spin and stellar surface…
