摘要: We present evidence from cosmological hydrodynamical simulations for a co-evolution of the slope total (dark and stellar) mass density profile, gamma (tot), dark matter fraction within half-mass radius, f(DM), in early-type galaxies. The relation can be described as gamma(tot) = A f(DM) + B all systems at redshifts. trend is set by decreasing importance gas dissipation towards lower redshifts more massive systems. Early-type galaxies are smaller, concentrated, have steeper high masses given redshift;f(DM) good indicators growth 'dry' merging. values change distinctively different feedback models, this used test such models. similar correlation exists between stellar surface Sigma(*). model with weak black holes best agreement observations. All simulations, independent assumed model, predict higher While latter observed trends, former conflict lensing observations, which indicate constant or gamma(tot). This discrepancy shown to artificial: trends reproduced using observational methodology calculate slopes.
