Abstract

We have mapped the radio emission in the error ellipse of GeV J1417-6100 (2EGS J1418-6049) at 13 and 20 cm using the Australia Telescope Compact Array. We find a large shell with extended wings, at the edge of which is a nonthermal, polarized structure with a center-filled morphology (the "Rabbit"), coincident with an extended, hard X-ray source. We discuss the various sources seen within the ellipse as potential counterparts of the γ-ray source. We conclude that the most likely scenario is that the Rabbit is a wind nebula surrounding a radio-quiet γ-ray pulsar.
