The Rotation of Spiral Galaxies [PDF]

Science, 1983
There is accumulating evidence that as much as 90 percent of the mass of the universe is nonluminous and is clumped, halo-like, around individual galaxies. The gravitational force of this dark matter is presumed to be responsible for the high rotational velocities of stars and gas in the disks of spiral galaxies.

Opaque spiral galaxies [PDF]

Nature, 1990
The photographic images of a carefully selected sample of about 16,000 galaxies have been digitized, and an extensive set of photometric parameters has been determined. These data allow a reanalysis of the effective transparency using the measured surface brightness profiles for much larger, more strictly defined samples. Several tests provide evidence

Spirals in galaxies

Proceedings of the International Astronomical Union, 2019
AbstractThe venerable problem of what causes the spiral features in disk galaxies is nearing a solution. In previous work, we have shown that transient spirals in simulations result from the superposition of a few coherent waves that have many properties of modes.

DYNAMICS OF SPIRAL GALAXIES

Frontiers of Applied Mathematics, 2007
The dynamics of spiral galaxies is a gold-mine of challenging problems for the astrophysicist and the applied mathematician. In Astrophysics, we may ask how these island-universes formed, evolved, and reached their current structure and thus address the problems of the dynamics of the interstellar medium, of star formation, of stellar dynamics, and of ...

Magnetism of spiral galaxies

Nature, 1988
The concept of the turbulent dynamo in interstellar gas combined with the discovery of global magnetic structures in spiral galaxies has led to a consistent picture of galactic magnetism. Large-scale magnetic fields are generated and maintained by helical turbulent motions of interstellar gas and by differential galactic rotation.

Opacity in Spiral Galaxies

Publications of the Astronomical Society of the Pacific, 1993
The global properties of galaxies such as their observed luminosities may be severely affected by internal obscuration of the stars by dust. In this thesis I examine the amount and extent of this obscuration using the following approaches: For a sample of eight galaxies for which I have obtained multi-waveband optical and near-infrared observations I ...
