We present a wide field, high resolution image of the Galactic Center region at 327 MHz. With a resolution of 7'' and an RMS noise of ~ 1.7 mJy beam-1, this image represents a significant increase in resolution and in sensitivity over previously published VLA images at comparable frequencies.
Using this new image, we have detected Nearly 100 previously unknown radio sources, at least a dozen non-thermal filament candidates which can be used to trace the Galactic Center magnetic field, A radio transient, and several steep spectrum sources that are pulsar candidates.
A low resolution version of a simultaneously obtained image at 74 MHz will also be presented, and will be reported on in further detail in a separate talk by C.L. Brogan. Further discussion of non-thermal filament morphology and orientation will be discussed in a seperate talk by T.N. LaRosa.
Basic research in radio astronomy at the Naval Research Laboratory is supported by the Office of Naval Research. The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities,Inc.
