Extended Data Fig. 5: The matter budget in massive halos.
From: A gas-rich cosmic web revealed by the partitioning of the missing baryons
We plot the fraction of matter bound in massive groups and galaxy clusters above a given mass, defined here as M500. The left vertical axis shows the fraction of cosmic baryons within r500 of halos with mass greater than M500. The right vertical axis shows the total matter bound in halos. The divergence at low masses is due to the apparent scarcity of baryons in smaller halos.
