Using the Jansky Very Large Array in recent years, Jun-Hui Zhao (CfA), Miller Goss (NRAO) and I have produced a 6-cm continuum map of the bright Sgr A complex that reveals far more detail than has previously been possible.  In this talk, I will describe the unanticipated results from this work, including a large population of new nonthermal filaments, and several magnetically-organized but highly distorted nonthermal filamentary stuctures that suggest the action of collimated outflows from the Galactic black hole, Sgr A*.   There is considerable evidence in both the radio map and a recent XMM X-ray survey that feedback from the Galactic black hole has a strong effect on the central tens of parsecs of the Galaxy, particularly in a direction perpendicular to the Galactic plane.  I’ll also describe new insights into the Sgr A East supernova remnant that appears to subsume Sgr A* within its volume, and shows a runaway neutron star that is the suspected remnant of the explosion.
