摘要: The local luminosity function was determined at v = 1.4 GHz from radio observations of two low-redshift galaxy samples: (1) spiral and irregular galaxies with apparent blue magnitudes declinations (2) all morphologies angular diameters 1.0 arcmin or greater in the declination range between -2.5 deg +82 deg. Separate functions for source populations powered by 'starbursts' 'monsters' were obtained latter sample. amount evolution required to account faint sources is discussed. cosmological extragalactic appears be so strong observed luminosities that counts S roughly 10 micro-Jy Jy can matched a model which most are confined hollow shell z 0.8. 36 refs.
