Low frequency polarization observations of the galactic radio emission.

Multifrequency polarization observations of a number of regions of the Galaxy in the frequency range 200-1250 MHz have been carried out. The area of enhanced linear polarization at meter wavelengths around α[sub 1950]=4[sup h]30[sup m], δ[sub 1950]=61° (l=146°47[sup ′],b=9°03[sup ′]) reveals a nonmonotonic, oscillating spectrum of the polarized brightness temperature. On the contrary, the region of the North Celestial Pole (l=123°,b=27°24[sup ′]) has practically monotonic spectrum. The possible reasons for this difference are discussed. © 2002 American Institute of Physics. [ABSTRACT FROM AUTHOR]
