Galaxies from the TNG50 simulation are categorized into three ranges based on their stellar halo fraction f_halo: f_halo<0.3, 0.3≤f_halo<0.6, and f_halo≥0.6. Galaxies with 0.3≤f_halo<0.6 were selected as the sample of Sombrero-like galaxies. The proportion of galaxies within different mass intervals is shown. The ratio of stellar halo fraction is considered within a range of 3R_e and the entire galaxy extent, represented by solid bar charts and dashed bar charts, respectively.
