                         subhaloes in the publicly available IllustrisTNG cosmological 
                         simulations (TNG100-1, TNG100-3, and TNG300-3), considering their 
                         full and dark-only versions, in redshifts ranging from z = 0 to z 
                         = 5, and different cell sizes. We evaluated two CiC models: the 
                         gravitational quasi-equilibrium distribution (GQED) and the 
                         negative binomial distribution (NBD), both presenting good fits, 
                         with small detectable differences in the presence of baryons. 
                         Scaling and time dependencies of the best-fitting parameters 
                         showed similar trends compared with the literature. We derived a 
                         matter density-in-cells probability distribution function (PDF), 
                         associated with the GQED, which was compared to the PDF proposed 
                         by Uhlemann et al., for the IllustrisTNG 100-3-Dark run at z = 0. 
                         Our results indicate that the simplest gravithermodynamical 
                         assumptions of the GQED model hold in the presence of baryonic 
                         dissipation. Interestingly, the smoothed (density-in-cells) 
                         version of the GQED is also adequate for describing the dark 
                         matter one-point statistics of subhaloes and converges, to 
                         subpercentage levels (for an interval of parameters), to the 
                         Uhlemann et al. PDF in the high density range.",
