“Radio Astronomy: Observing the Center of the Milky Way” 

Abstract: Radio wavelength studies of the center of the Milky Way have been completed for over half a century. Despite a wealth of observations, the dynamic interactions occurring near the heart of our galaxy are still poorly understood. A peculiar structure known as the Galactic Center Radio Arc was formed as a result of intense gravitational fields, rapid star formation and the potential influence by dark matter. Using the Very Large Array, a multi-frequency, spectro-polarimetric study was completed in order to better understand the nature and formation of these structures.
