Book Description
The interferometer at the Owens Valley Radio Observatory has been used to study the linear polarization of 54 radio sources at a wavelength of 10.6 cm. The measurements were made with two 90-ft antennas spaced 100 feet (289 lambda) in the east-west direction. (Author).

The Connection Between Linear Polarization and Galactic Latitude of Discrete Radio Sources

Languages : en
Pages : 8
Book Description
The degree of linear polarization at a wavelength of about 21 cm is considered for 166 presumably extragalactic radio sources. A connection between degree of linear polarization and galactic latitude is found; low-latitude sources tend to show a lwer degree of polarization than high-latitude sources. It is found that the correlation between degree of polarizatin and galactic latitude is weaker at a wavelength equal to 10 cm than at 21 cm. This result is derived from a sample of 46 sources observed at both wavelengths. Possible interpretations of the correlation found at 21 cm are discussed. (Author).

Preliminary Measurements on the Distribution of Linear Polarization Over Eight Radio Sources
Author: D. Morris
Publisher:
ISBN:
Category :
Languages : en
Pages : 15
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
A list of linear polarization measurements for 66 radio sources is presented. It includes values for 39 sources not previously reported on, plus a more complete set of values for sources previously described. Of these sources, approximately 40 have been examined at three different warelengths (10, 18 and 21 cm) and for those with appreciable polarization in this range the dependence of polarization on wavelength is given. The relationship between the major axis position angle and the intrinsic polarization angle of double radio sources is discussed.

Pages : 18
Book Description
Linear polarization measurements at 6 cm wavelength with the Parkes 210 ft telescope are given for 706 sources. Comparison of polarization parameters and flux densities with other published data is made. For the variable sources it is found that changes in polarized flux and position angle can accompany changes in intensity. (Author).
