Our Galactic center's proximity allows astronomers to study physical pro- cesses within galactic nuclei at a level of detail that will never be possible in the more distant, but usually also more spectacular, extragalactic systems. Recent advances in instrumentation from the radio, through the submillime- ter and infrared wavebands, and out to the X- and "'(-ray bands now allow observations of the Galactic Center over thirteen orders of magnitude in wave- length. Our knowledge about the central few hundred parsecs of our Galaxy has consequently increased vastly over the past decade. The same...
