Sketch of the 12 central parsecs of the Galaxy. Gray regions represents radio continuum features. Big ellipses correspond to the SNRs Sgr A East and G 359.92−0.09, the central minispiral to the H ii region Sgr A West, and the four little circles to the Sgr A East compact H ii regions. The central star represents Sgr A^∗. Molecular gas features are represented by stripped regions, whereas red arrows toward the center point out the possible connections between the CND (the elliptic disk) and the CMCs of this region. See the text for more details.
