Mapping the Milky Way and the Local Grouprces separated by about 1° are being measured with accuracies of ~ 10 μas. With this accuracy, trigonometric parallaxes throughout the Milky Way and proper motions of Local Group galaxies are now being measured. These observations will lead to direct mapping of the structure of the Milky Way, testin

Dynamics of Stars in the Inner Galactic Bulge Revealed from SiO Maser Surveysities of ~160 detected objects. The longitude–velocity diagram of these objects reveals two conspicuous features: one indicating a linear velocity increase with longitude with |.| < 1.5°, which is likely to be associated with the inner bar, and the other having eccentric velocities with |..| >250 km

The Physics of Cold Gas in Galaxy Low Excitation Regionsiate to return considering the simplest situations. The low excitation regions in or around galaxies, such as the galaxy outer disks, the inter-arm regions, the well shielded starless cores in molecular clouds, or the high velocity clouds (HVC’), appear as ideally suited to test our understanding of

Secular Evolution of Disc Galaxies and of their Componentsnsistent .-body simulations. When the bar forms, it is as thin as the disc. Its three-dimensional shape, however, evolves, so that, at later times, it has a thick inner part and a thin, more extended outer part. The former, when viewed edge-on, is called a boxy/peanut bulge, because of its shape. Th

Numerical Modeling of the ISM in the Galactic Center and Disksscussed. 3-D hydrodynamic simulations show that the PDFs in globally stable, inhomogeneous ISM in galactic disks are well fitted by a single log-normal function over a wide density range. The dispersion of the log-normal PDF (LN-PDF) is larger for more gas-rich systems, whereas the characteristic de
