| Popis: | We analyse processes of particle acceleration in the Fermi Bubbles. The goal of our investigations is to obtain restrictions for acceleration mechanisms. Our analysis of the three processes: acceleration from background plasma, re-acceleration of relativistic electrons emitted by supernova remnants, and acceleration by shocks generated by processes of star tidal disruption in the Galactic Center, showed that the model of multi-shock acceleration does not have serious objections at present and therefore seems us more attractive than others. Comment: The text is pepared for publication in the Proceedings of IAU Symposium 303 "The Galactic Center: Feeding and Feedback in a Normal Galactic Nucleus", Santa Fe, USA, 2013 |
