EMISSION SPECTRA OF DISCRETE SOURCES CASSIOPEIA-A, CYGNUS-A, TAURUS-A, VIRGO-A AT 12.5-40 MC FREQUENCIES,

Abstract

For four discrete radio sources, results of measuring radiation in a 12.5 - 40 mc band are given. A characteristic decrease in the spectra of three sources at frequencies below 20 - 25 mc is noted. The results are used to calculate the characteristic parameters of the sources (emissivity and ratio H /n sub e) under the assumption that a decrease in the spectrum is caused either by absorption in clouds H sub H or by a decrease in the refractive index at the source.
