Dark Matter from the Observational Perspective

摘要

I review the properties of dark matter in galaxies from an observational perspective. Topics include the mass and extent of the dark halos of large spirals like the Milky Way, modelling the dark halo, the maximum disk problem, the hydrostatics of the HI layer in disk galaxies as a probe of the galactic potential, dark matter in elliptical galaxies and dwarf spheroidal galaxies, scaling laws for dark halos, and the fractional contribution of galactic dark matter to the mass content of the universe.
