Low-frequency radio spectra of crab nebula, Virgo A, and Cygnus A

  • Published:
Radiophysics and Quantum Electronics Aims and scope

Abstract

The results of absolute flux density measurements are presented for discrete radio sources 3C 144, 3C 274, and 3C 405 at 5.6 and 8.9 MHz. The new data are used in the discussion of their low-frequency radio spectra to specify physical conditions in radio galaxies Virgo A, Cygnus A, and supernova remnant Crab nebula.
