M Giant Kinematics in Off-axis Fields between 150 and 300 PC from the Galactic Centers., 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 match Kent’s (1992) axisymmetric mass model but may be higher than the model’s predictions at small projected radius.

Results of the SiO Maser Survey of the Galactic Bulge IRAS Sources found yet. At optical wavelengths, stellar radial velocities of the bulge stars were observed only at the optical windows and were not observed for the entire region of the bulge because of the dust extinction in this direction.

Faint Surface Photometry of the Halo of M31[itp(.) ∝ R.. This result suggests that the globular cluster component of the halo of M31 (for which . ∝ ..) is more extended than the stellar halo of this galaxy. At μ. ≈ 28 mag arcsec. (. ≈ 10 kpc), the axial ratio of the halo of M31 is found to be ./. = 0.55 ± 0.05.

Results from the Optical Gravitational Lensing Experiment (OGLE) OGLE events are related to dark matter . The OGLE color magnitude diagrams reveal the presence of the Galactic bar and a low density inner disk region ~ 4 kpc in radius. A catalogue of a few thousand variable stars is in preparation.
