DM fraction, f_DM, as a function of the circular velocity at the effective radius, V_circ(R_e) (left), and baryonic surface density, Σ_bary (right). The yellow and blue curves show the TNG100 (without adiabatic contraction) relations at z = 0 and z = 2 (Lovell et al. 2018), respectively. The pale blue and red shadings are measurements from RC100 at z < 1.2 and z < 2.5, respectively (Nestor Shachar et al. 2023). The thick grey dashed curve is the best-fit relation of z ∼ 2 star-forming galaxies from Wuyts et al. (2016). The CRISTAL sample statistics suggest a tentative anti-correlation with f_DM(R_e) and Σ_bary, although individual galaxy uncertainties are limited by the data depth. The horizontal dashed line denotes f_DM for a maximal disk f_DM ≔ 28% (van Albada et al. 1985). In the right panel, the two symbols plotted with only limit arrows represent CRISTAL-10a-E (upper limit) and CRISTAL-06b (lower limit). The stellar mass is only for CRISTAL-10a as a whole, which includes CRISTAL-10a-E, while no gas mass is available for CRISTAL-06b.
