6cm and 20cm survey of Galactic Center

Catalogs of compact and filamentary structures are given and compared to previous surveys of the region. Eight of the unusual nonthermal radio filaments are detected in 6cm polarized emission; three of these are the first such detections, confirming their nonthermal nature.

This survey found emission from a filament at (l,b)=(359.1,0.75), or a projected distance from Sgr A* of 200pc, greatly extending the latitude range observed with such features. There is also new evidence for spatial gradients in the 6/20cm spectral indices of some filaments, and we discuss models for these gradients. In studying compact sources, the combination of spectral index and polarization information allows us to identify pulsar candidates and compact HII regions in the survey.
