GBT Multiwavelength Survey of the Galactic Center Region

Understand

We describe the results of a radio continuum survey of the central 4x1deg with the 100 m Green Bank Telescope (GBT) at wavelengths of 3.5, 6, 20, and 90 cm.

• The 3.5 and 6 cm surveys are the most sensitive and highest resolution single dish surveys made of the central degrees of our Galaxy.
• We present catalogs of compact and extended sources in the central four degrees of our Galaxy, including detailed spectral index studies of all sources.
• The analysis covers star-forming regions such as Sgr B and Sgr C where we find evidence of a mixture of thermal and nonthermal emission.
