Reports on Progress in Physics, 1973
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 attempt to understand galaxies in general.

In this contribution I will review the state of the field of structure of galaxies in general terms. I will concentrate on open questions rather than recent achievements. The discussion will not be aimed at experts in the field, but at a rather broader audience.

The Structure and Rotation of the Galaxy
Publications of the Astronomical Society of the Pacific, 1932For uncounted generations thoughtful men, philosophers and mathematicians, physicists and astronomers, as well as many other students, have been puzzling over the nature of our surroundings in space. They have not been satisfied, as I am afraid many of us are satisfied, with their merely terrestrial surroundings but have tiied to penetrate the almost ...

Tracing the spiral structure of our Galaxy requires to identify and position the star-forming complexes. Each complex can be seen as a parental molecular cloud with associated ionised hydrogen, young stars and young clusters. The analysis of the ionised gas at Halpha wavelength (diffuse emission as well as discrete HII regions) is essential to ...

The Spiral Structure of Galaxies
1995About two-thirds of all galaxies are spiral galaxies, and a large number of them, more than two-thirds, have a regular spiral structure with two arms that can be followed continuously from the centre of the galaxy (the central bulge) to the extremities of the disc.

The Structure of Elliptical Galaxies
1988Recent imaging investigations highlight the structural diversity of elliptical galaxies. The distribution of light within the cores and envelopes shows a wide range in central and average system stellar densities at any galaxy luminosity. These variations appear to offer new information on galaxy formation mechanisms.
