Abstract

A MERLIN map with 50 mas resolution at 5 GHz together with VLA maps at other frequencies show that 0218+357 is a gravitationally lensed system with two unresolved images of a compact core separated by 335 mas, plus an Einstein ring of similar diameter. The separation is smaller by a factor > 3 than any previously reported.
