Subhalo-to-stellar mass relation (SHSMR) for satellite galaxies in galaxy clusters with masses M_200m > 10¹³ M_⊙ in the EAGLE simulation. The coloured background shows the occupation of the m_sub − m_⋆ plane, while the thick blue line shows the best-fitting Eq. (1), which has been fit only over the range in which the blue line is solid. The dashed magenta line shows the corresponding fit to central galaxies while black dots show the centrals in the M_200m > 10¹³ M_⊙ clusters included in this work. The dashed black line black line shows the satellite SHSMR in IllustrisTNG (Niemiec et al. 2022) and large circles with error bars show the weak lensing measurements of Sifón et al. (2018). The inset shows the logarithmic scatter around the mean relation, which can be approximated by a lognormal distribution with standard deviation σ = 0.41.
