Investigation of the Baryonic Mass Tully–Fisher Relationship for Normal and Barred Spiral Galaxies

Abstract

     In this study, the stellar mass M*(L_B) and the atomic gas mass M_HI (L_B) were utilized to evaluate the baryonic mass Tully–Fisher (M_b) of disc system spiral galaxies (for normal spiral and barred spirals) and to obtain an empirical relation between masses M_b, M_HI, M* and optical luminosity at blue range L_B. The data for the studied sample was collected from literature papers for unbarred (normal) and barred-type morphological spiral galaxies. Therefore, in this work, the sample of data was chosen to analyze the baryonic mass Tully–Fisher relationship for normal and barred spiral galaxies. Statistical analysis of the connections was used between the stellar mass M*, the baryonic mass of disk spiral systems (M_b), and the M_HI for cold gas content. This study shows that there are certain relations and strong interconnections between the maximum and minimum baryonic mass ranges between M_bmax (L_B) ≈ 1.4x10¹² M_ʘ and M_bmin (L_B) ≈ 2x10⁹ M_ʘ for barred, while M_bmax (L_B) ≈ 6x10¹¹ M_ʘ and M_bmin (L_B) ≈ 5x10⁹ M_ʘ for unbarred spirals. Also, there are strong significant correlations between (Log M* - Log L_B and Log M_b - Log L_B). Finally, the analysis of the result demonstrates a strong partial coefficient correlation (R ~ 0.9) between the logarithmic scales relationships of baryonic mass (M_b) and the neutral cold gas mass )M_HI (for barred and unbarred spirals with a slope equal to 1.
