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…
Halo Spin Dependence on Environment for HI-bearing galaxies
Zichen Hua, Yu Rong, Huijie Hu
Leveraging the semi-analytic method, we compute halo spins for a substantial sample of HI-bearing galaxies observed in the Arecibo Legacy Fast Alfa Survey. Our statistical analysis…
Ultra Diffuse Dwarf Galaxies Hosting Pseudo-bulges
Yu Rong, Hong-Xin Zhang, Cheng Cheng +5
By analyzing data from DESI Legacy Imaging Survey of the dwarf galaxies in the Arecibo Legacy Fast Alfa Survey, we have identified five ultra-diffuse galaxies (UDGs) featuring cent…
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…
