Lens galaxies in the Illustris simulation: power-law models and the bias of the Hubble constant from time delays

A power-law density model, i.e. $$\rho (r) \propto r^{-\gamma ^{\prime }}$$, has been commonly employed in strong gravitational lensing studies, including the so-called time-delay technique used to infer the Hubble constant H0. However, since the radial scale at which strong lensing features are for...
