Abstract
Abstract: This poster presents a new 5 GHz combined MERLIN/VLA map of B0218+357 which shows for the first time believable substructure in the Einstein ring. This will now be exploited for further constraints on the model which presently dominates the error on the estimate of H_0 derived from the time delay (10.5+/-0.4 days) measured for this system.
