[28.08] The FIRST-Optical-VLA Survey for Gravitationally Lensed Radio Lobes

D.B. Haarsma (Calvin College), FOV Survey Team

In this survey, we select potential radio lobes from the FIRST catalog, search deep optical catalogs for coincident optical objects (the potential foreground lens galaxies), and then obtain high resolution images of these systems at radio and optical wavelengths. This strategy allows us to discover lensed radio lobes with an efficiency similar to surveys for lensed radio point surces, but the lenses we discover can provide richer constraints on the lens galaxy mass distribution. We present maps of several radio lobes with coincident galaxies, including one lobe (FOV J0743+1553) that is strongly lensed by a spiral galaxy at redshift 0.19.
