In this paper, we extend the work of Freundlich et al. 2020 who showed how toobtain a Dekel-Zhao density profile with mass dependent shape parameters in thecase of galaxies. In the case of Freundlich et al. 2020, the baryonicdependence was obtained using the NIHAO set of simulations. In our case, weused simulations based on a model of ours. Following Freundlich et al. 2020, weobtained the dependence from baryon physics of the two shape parameters,obtaining in this way a mass dependent Dekel-Zhao profile describing the darkmatter profiles from galaxies to clusters of galaxies. The extension to theDekel-Zhao mass dependent profile to clusters of galaxies is the main result ofthe paper. In the paper, we show how the Dekel-Zhao mass dependent profilegives a good description of the density profiles of galaxies, already shown byFreundlich et al. 2020, but also to a set of clusters of galaxies.
