A Theory of Bending Waves with Applications to Disk Galaxies

  title={A Theory of Bending Waves with Applications to Disk Galaxies},
  author={James W.-K. Mark},
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 galaxies. The shape of observed warps and partly their existence in isolated galaxies are indicative of substantial spheroidal components. The theory also provides a plausible explanation for the bending of the inner disk (< 2 kpc) of the Milky Way.

The Thickness of Galactic Disks
The local dynamical structure of disk galaxies is broadly characterized by a vertical scale height which is nearly independent of radius, the scale height being about 1/10 of the horizontal scale
The Structure of Our Galaxy Derived from Observations of Neutral Hydrogen
Although insight into the structure of our Galaxy can be sought in various ways, study of the radio emission from the neutral hydrogen component is particularly suitable. Neutral atomic hydrogen, HI,

The mechanisms for the maintenance and the excitation of trailing spiral modes of density waves in diskshaped galaxies are substantiated by an analysis of the gas-dynamical model of the galaxy.
Aperture synthesis of neutral hydrogen in the galaxy M33
Observations of neutral hydrogen in the galaxy M33 with resolutions of 2' and 10 km s/sup -1/ are described. Detailed modeling has revealed weak evidence for spiral density waves with an arm-interarm
Can galaxy warps be used to provide constraints on halo properties?
The prevalence of flat rotation curves in external galaxies1 strongly suggests an extensive but as yet unseen halo component. However, as direct observations of the implied matter distribution have
The hose-pipe instability in stellar systems
Indications are that instabilities play an important role in many of the phenomena of stellar dynamics. Examples of such phenomena are: the formation of spiral arms, and the evolution of stellar
Discrete spiral modes in disk galaxies: Some numerical examples based on density wave theory.
From the growth rates obtained, it appears likely that several spiral modes coexist in a given disk galaxy, according to the recently developed asymptotic theory of density waves for spiral structure in galaxies.
Twisted and warped disks as consequences of heavy halos. [galactic structure
Observationally testable consequences of the hypothesis that galactic disks are confined less by their self-gravity than that of some hot stellar component are sought. Theoretical and observational

Through outward transport of angular momentum, the circular rotation in disk galaxies becomes an abundant ''source'' for spiral density waves. Increases in wave angular momentum of an order of
Persistence of gaseous warps
Galactic warps of the gaseous component beyond the boundary of a finite stellar disk or at radii greater than 5 radial scale heights in an exponential disk can persist for several rotation times. The
On Density Waves in Galaxies. 11. the Turning-Point Problem at the Corotation Region
A more careful analysis has been made of the galactic density waves near the corotation region where the wave pattern speeds are the same as the local circular speed of the disk. Some ambiguities
Why is the central gas disk of the Galaxy tilted?
Independent analyses of the HI and CO within 2 kpc of the galactic centre have shown that the gas distribution is best described as a disk-like structure with a rotation axis inclined 20–25° to that
