Book Description
The feasibility of the determination of polarization distributions over radio sources by variable spacing interference polarimetry was tested. The results of preliminary measurements for eight strong sources are presented. The polarized region in the Crab Nebula at 10.6-cm wavelength is roughly one-half the diameter of the unpolarized source. Both components of the central source in Centaurus A are found to be linearly polarized, but with their planes of polarization at 44 degrees to each other. The observations on five other double sources, 3C 270, Pictor A, Hercules A, 3C 353 and Cygnus A show evidence of two or more polarized regions on each source with different preferred directions. M87, the galaxy with the optically polarized 'jet', seems to have a polarized halo at 21 cm whereas earlier measurements at the same wavelength had indicated that the core was essentially unpolarized.

Book Description
“The polarization study of celestial objects is a valuable part of optical astronomy, and the author has done exceptionally well in bringing together contributions treating all aspects of the polarimetry field. . . . The first section contains a fine introduction and an excellent and definitive history of the subject. . . . The volume is well illustrated. . . . Highly recommended.”—Choice “The high quality of this book is clearly due to strict editorial attention to each paper and the discussions. Gehrels’s book will surely stand for many years as the fundamental reference source for polarization studies in astronomy as well as in atmospheric physics.”—Journal of the Association of Lunar and Planetary Observers
