PBH mass function as a function of the primordial black hole mass (left panel) and the fraction of dark matter composed of these objects (right panel). In both panels, these estimates are obtained assuming Eddington-limited accretion onto all black holes observed by the JWST (solid line; upper limit) and for those that cannot be explained by Eddington-limited accretion onto low-mass seeds (dashed line) and intermediate-mass seeds (point). As shown by arrows in the left panel, super-Eddington accretion would shift the mass function towards lower masses. Decreasing the seeding redshift would shift the mass function to higher masses.
