Wide-field EVN observations of the gravitational lens system 2016 + 112

We present a wide-field λ18-cm European VLBI Network (EVN) map of the gravitational lens system 2016 + 112. The map shows the main regions of radio emission previously designated A, B, C1 and C2. C2 may be a third lensed radio image. C1 is clearly resolved into three main components C11, C12 and C13...

Zusammenfassung:We present a wide-field λ18-cm European VLBI Network (EVN) map of the gravitational lens system 2016 + 112. The map shows the main regions of radio emission previously designated A, B, C1 and C2. C2 may be a third lensed radio image. C1 is clearly resolved into three main components C11, C12 and C13. The nature of C1 is unclear, but its peculiar radio structure favours a lensing interpretation.
