DM core density vs. core radius relation of local and high-z galaxies. The blue circles and hexagons represent the z ∼ 1 individual and coadded RCs, respectively. The coral red circles and stars represent the local star-forming and low surface brightness galaxies (Persic et al. 1996; Di Paolo et al. 2019), respectively. The brown dashed line is the best fit to z ∼ 1 data with a slope α = −1.54, and the orange shaded area represents the 1 − 3σ intrinsic scatter in the relation.
