Abstract

A sensitive λ 20cm VLA continuum survey of the Galactic center region, based on multi-configuration observations, are presented. The high dynamic range images cover the regions within -2o < l < 5o and -40' < b < 40' with spatial resolutions of ≈30'' and 10''. The wide field imaging technique is used to construct a low-resolution mosaic of 40 overlapping pointings combined with the GBT data filling the missing zero-spacing data. We show high dynamic range images of a number of prominent objects in this region, including Sgr A, B, C, D, and E.
