A time delay for the cluster-lensed quasar SDSS J1004+4112
We present 426 epochs of optical monitoring data spanning 1000 days from 2003 December to 2006 June for the gravitationally lensed quasar SDSS J1004+4112. The time delay between the A and B images is ΔtBA = 38.4 ± 2.0 days (Δχ2 = 4) in the expected sense that B leads A and the overall time ordering...
