Extended Data Fig. 4: Comparison between the relations of BH masses to the HI gas fraction and to the total gas fraction.
From: Black holes regulate cool gas accretion in massive galaxies
The relation between MBH and HI gas fraction is shown in panel a, and the relation between MBH and total gas fraction is shown in panel b for central galaxies. The blue circles and red squares denote respectively star-forming and quiescent galaxies, which are classified based on their SSFR. Spearman correlation coefficients and the RMS between data and the fitted relations (black dashed lines) are shown in the top-right corners. The error bars refer to 1-σ errors.
