Spectral properties and the effect on redshift cut-off of compact active galactic nuclei from the AT20G survey
Spectral index has been traditionally used to separate extragalactic radio sources into compact and extended populations, with the spectral transition placed variably between -0.4 and -0.6. We use high angular resolution data, measured from visibility of sources at the longest baseline of 4500 m of...
