  1. A 325 MHz Radio Survey of M31 Yosi Gelfand (CfA) Joseph Lazio (NRL) Bryan Gaensler (CfA) • Using the VLA A-array, we imaged 405 radio sources in the field of M31 with a resolution 6” and a sensitivity of 0.6 mJy/beam. • 38 are X-ray sources from ROSAT, Chandra, and XMM observations of the area. • We have identified in this field • SNR and PWNe candidates (see poster), several with X-ray counterparts • FRI, FRII radio galaxies, and radio emission from star-forming galaxies with X-ray counterparts • USS, CSS, and GPS sources, some with X-ray counterparts. • BL-Lac and Galaxy Merger with X-ray counterparts • And a large number of anomalous sources, inc. very steep spectrum sources, extremely variable sources, and source with bizarre morphologies.
