MG (JVAS rediscovery) MG0414+0534, a quad image gravitational lens



Lens System Summary

MG0414+0534 is a quadruple image lens. It was discovered in the MG radio survey. It was re-discovered during the JVAS. This lens is not part of the statistically complete CLASS sample since its radio spectrum is too steep.
