Weak lensing observations of the "dark"cluster MG 2016+112
We investigate the possible existence of a high-redshift () cluster of galaxies associated with the QSO lens system MG 2016+112. From an ultra-deep R- and less deep V- and I-band Keck images and a K-band mosaic from UKIRT, we detect ten galaxies with colors consistent with the lensing galaxy within …
