Number of satellite galaxies as function of the host’s galaxy stellar mass colour-coded by the host galaxy bulge-to-total mass ratio (B/T). Note that the y-axis switches from linear to logarithmic scaling at N_sat = 1. The black line shows a power law fit, while the shaded region indicates the 95% confidence interval, estimated from the NB regression. For comparison we include the values of the MW and Andromeda galaxies. The stellar masses have been obtained from Licquia & Newman (2015) and Sick et al. (2015) respectively. The satellite number counts were obtained from the Pace (2025) database, mimicking our satellite selection criteria (see Section 3.2).
