X-ray surface brightness profiles of the hot CGM of the central star-forming (SX, CGM, SF, blue) and quiescent (SX, CGM, QU, red) galaxies with M* ∈ 10.5 − 11.0, 11.0 − 11.25 and 11.25 − 11.5 (top left, top right, and bottom left). The vertical dash-dotted (dotted) lines denote the average R500c (Rvir) of stacked central galaxies. The median redshift (), median M200 m and median M* are denoted for star-forming and quiescent respectively. Hot CGM X-ray luminosity of central star-forming galaxies (LX, CGM, SF, blue) and quiescent galaxies (LX, CGM, QU, red) within R500c in 0.5 − 2 keV as a function of the M*, compared to the LX, CGM − M* scaling relation from Zhang et al. (2024b) (bottom right).
