Intrinsic Degeneracy of Gravitational Lens Time Delays: the case for a simple quadruple system in CDM cosmology

HongSheng Zhao, Bo Qin

A degeneracy in strong lens model is shown analytically. The observed time delays and quasar image positions might {\it not} uniquely determine the concentration and the extent of…
