Dark Matter in Galaxies: Observational overview

Abstract

I review the observational side of the present state of the debate about the dark matter in galaxies, with emphasis on the core/cusp problem in low surface brightness galaxies, and the question of maximum / sub-maximum disks in spiral galaxies. Some remarks are made about the dwarf spheroidals around the Milky Way, and about elliptical galaxies.

12 pages, 4 figures, includes style file, invited review at IAU Symposium 220, eds. S. Ryder, D.J. Pisano, M. Walker & K.C. Freeman, has 2 page appendix with historical notes
