Infinitesimal bending oscillations and/or responses of thin rotating disks applied to thin disk galaxies, discussing Magellanic Cloud passage near galactic center 
Large Scale Oscillations of Galaxies
The observational evidence that may indicate the presence of large scale modes of oscillation in galaxies is reviewed, and some results of theoretical modal calculations are described.
Gravitational interactions between galaxies
Recent theoretical studies of the consequences of fierce tidal interactions between galaxies are reviewed and compared.
Outer Spiral Structure and High Velocity Clouds in the Galaxy
New observations of high velocity clouds show that these may be interpreted in terms of an extension of the outermost spiral arm, confirming and extending the model of Habing.
Amplification of spiral density waves in gaseous and dust galactic disks as a result of interaction with the halo
The effect of the discrete structure of the halo on local oscillations of a galactic disk is analyzed. Such effects have much in common with dynamical friction. Gaseous and stellar disks are
Stellar Hydrodynamic Equations for a Thin Disk Galaxy
Assuming that the motions of stars depart only slightly from circular, finite closed systems of stellar hydrodynamic equations are obtained for a disk galaxy by taking moments of the collisionless
The Outer Spiral Structure of the Galaxy and the High-Velocity Clouds
Outer spiral arms have been mapped using high sensitivity observations. Their velocity and location suggest a close association with the high-velocity clouds (HVCs).
A Theory of Bending Waves with Applications to Disk Galaxies
A theory of bending waves is surveyed which provides an explanation for the required amplification of the warp in the Milky Way. It also provides for self-generated warps in isolated external
Generation of Warps by Accretion Flows
We present ample evidence for the presence of continuing gaseous infall to the Galactic plane, and then show how interaction of this gas with the disc gas yields a warp of the observed amplitude and
Structure of the galaxy
The authors have summarized the present knowledge of the stellar content of our galaxy and discussed at some length the use of this knowledge in creating a dynamical framework that can be used in the
Statistical significance of some optical evidence for the bending of the galactic plane
It is argued on the basis of an analysis of variance test that the distribution of Wolf-Rayet stars in the Galaxy departs systematically from the plane in the same sense as the neutral hydrogen.
