M Giant Kinematics in Off-axis Fields between 150 and 300 PC from the Galactic Centerentric radial velocity and velocity dispersion are −75 ± 24 km s. and 127 ± 16 km s., 2 ± 23 km s. and 127 ± 14 km s., −14 ± 22 km s. and 126 ± 14 km s., and −31 ± 28 km s. and 153 ± 17 km s. for fields located at 299, 288, 171, and 160 pc projected radius, respectively. The dispersions generally ma

Results of the SiO Maser Survey of the Galactic Bulge IRAS Sources. (1991) based on IRAS point source catalogue, and more clearly by recent LOBE maps. However, no clear “dynamical” signature of the bulge bar has been found yet. At optical wavelengths, stellar radial velocities of the bulge stars were observed only at the optical windows and were not observed for t

3D N-Body Simulations of the Milky Waygular speed etc...) still remain controversial. The large amount of photometrical and stellar kinematical data becoming now available within ∼30° of the Galactic Centre should provide potentially new constraints on these parameters. Unfortunately, a detailed barred model of the Milky Way, which woul

A Survey of Surveysn Sky (DENIS) and the Two Micron All Sky Survey (2MASS). These surveys will permit detailed studies of Galactic structure and stellar populations in the Galaxy with unprecedented detail. Extracting the information, however, will be challenging.

Is There a Bulge Distinct from the Bar? the distortion pointing somewhere in the first Galactic quadrant. It is therefore tempting to reconsider our data concerning this part of the Galaxy in terms of ‘the’ Bar. But to what extent should we (or is it useful to) distinguish between the bar and the stellar bulge of old?
