Radiation Pattern of Radio and Optical Components of Extended Radio Sources

摘要

The relation between parameters the D/sqrt(I) and Ic/Isum and radiationpatterns of the optical and radio components of an extended radio source isanalyzed, where D and I are the apparent size and observed radiation intensityof the source or its components respectively. The parameters of the pattern inthe optical and radio (1.4 GHz) ranges are estimated. The radiation pattern ofextended radio-emitting regions is close to spherical and the radiation of thecentral component is concentrated in a 24 degrees wide beam. Its luminosity isa factor of 4.58 higher than that of the extended component of the radiosource. The radiation pattern of the optical component of the radio sourceturned out to be unexpectedly non-spherical: the main lobe of the pattern isabout 26 degrees wide. The g-band luminosity is 6.4-12.3 times higher than theluminosity of the spherical fraction of the "optical" radiation pattern. A listof 116 new giant radio sources is presented.
