An X-ray Chimney Extending Hundreds of Parsecs Above and Below the Galactic Center

Thursday February 21, 2019
2:00 pm

 Presenter:  Mark Morris, UCLA
 Series:  Center for Astrophysics Research and Technologies Seminar Series
 Abstract:  X-ray mapping observations of the Galactic center with the XMM-Newton X-ray Satellite show a “chimney” of X-ray emission centered on Sgr A* and extending a few hundred parsecs perpendicular to the Galactic plane in both directions.  We (Gabriele Ponti et al. 2019) interpret this as an exhaust channel containing a hot plasma generated by activity associated with the Galactic Black Hole.  This channel extends to the gamma-ray-emitting Fermi Bubbles, and may be the conduit through which relativistic particles travel to energize those gigantic features.
