Abstract (from CDS):

We present Hubble Space Telescope images and 2 years of optical photometry of the quadruple quasar HE 0435-1223. The time delays between the intrinsic quasar variations are ΔtAD=-14.37+0.75–0.85, ΔtAB=-8.00+0.73–0.82, and ΔtAC=-2.10+0.78–0.71days. We also observed nonintrinsic variations of ∼0.1 mag/yr that we attribute to microlensing. Instead of the traditional approach of assuming a rotation curve for the lens galaxy and then deriving the Hubble constant (H0), we assume H0=(72±7) km/s/Mpc and derive constraints on the rotation curve. On the scale over which the lensed images occur (1".2=5 h–1 kpc≃1.5Re), the lens galaxy must have a rising rotation curve, and it cannot have a constant mass-to-light ratio. These results add to the evidence that the structures of early-type galaxies are heterogeneous.
