X-ray luminosity vs. stellar mass. The hot CGM X-ray luminosity (L_X, CGM) measured around the central galaxies (CEN sample) within R_500c in 0.5 − 2 keV as a function of the M_* is shown in purple. The purple band displays the best-fit single power law model and its 1σ uncertainty. The modeled X-ray luminosity from unresolved AGN, XRB (L_{X, AGN + XRB + SAT}) is depicted in tan. The L_X, CGM − M_* measurements from Anderson et al. (2015) are plotted with thin brown crosses, notice the M_* is shifted by 0.1 dex to higher mass to account for the difference in M_* estimation between Anderson et al. (2015) and this work. The prediction from the EAGLE, TNG100 and SIMBA simulations compiled following the methodology of Truong et al. (2023) are overplotted with 1σ uncertainties.
