Magnetic Fields in Diffuse H I and Molecular Clouds

Abstract

This book chapter reviews the current state of observations of magnetic fields in diffuse H I and in dense molecular clouds. It covers techniques for measuring magnetic fields, the analysis of the observations, and the role of magnetic fields in the physics of interstellar clouds and in the star formation process.

50 pages, 14 figures, to be published as book chapter in 'Cosmic Magnetic Fields'
