Abstract:

We present a wide-field, subarcminute-resolution VLA image of the Galactic center region at 330 MHz. With a resolution of -7 x 12 and an rms noise of 1.6 mJy beam exp -1, this image represents a significant increase in resolution and sensitivity over the previously published VLA image at this frequency. The improved sensitivity has more than tripled the census of small-diameter sources in the region, has resulted in the detection of two new nonthermal filaments NTFs, 18 NTF candidates, and 30 pulsar candidates, reveals previously known extended sources in greater detail, and has resulted in the first detection of Sagittarius A in this frequency range.
