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 ...

The disks of spiral galaxies

Vistas in Astronomy, 1986
Abstract This article aims to give an overview of the present state of knowledge about the disks of spiral galaxies obtained from a very large number of observations at various wavelengths. Theoretical ideas which are essential for an understanding of much of the observational material are sketched in sections 2 and 3.

Phenomenology of Spiral Galaxies

1975
Galaxies have probably been formed from fluctuations in density and motion in the universe. Many cosmologists have suggested that the separation into individual units took place around the time of decoupling of matter and radiation, when the radius of the universe was about 1/1000th of the present radius.
