Mapping Outflowing Cool Gas in the Fermi Bubbles
Abstract
The Fermi Bubbles are an example of extreme feedback in our own Milky Way. These two giant bubbles extend ~10 kpc above and below the center of the Galaxy. They are thought to have formed via an outburst from our central supermassive black hole or nuclear star formation. Understanding the origins of the Fermi Bubbles requires careful measurements of their kinematics and chemical abundances. We have obtained FUV spectra from Hubble/COS to characterize the previously unexplored low latitude region of the southern Fermi Bubble, close to where the bubbles are launched. With these data we measured the kinematics and composition of the southern bubble and how they vary with both Galactic latitude and longitude. Combining these results with our ongoing multiwavelength program to characterize the Fermi Bubbles at all latitudes will give us a more complete picture of the multiphase gas flows and their impact on the Galaxy.
