2016+112: a gravitationally lensed type II quasar
A single-screen model of the gravitational lens system 2016+112 is proposed, that explains recent Hubble Space Telescope (HST) infrared (NICMOSā€“F160W) observations and new high-resolution European VLBI Network (EVN) 5-GHz radio observations, presented in this paper. In particular, we find that a massive 'dark' structure at the lens position, previously suggested ā€¦
