High-resolution observations of quasars from the Parkes +/- 4 deg. sample

Booth, R. S.University of Manchester, Nuffield Radio Astronomy Laboratories, Jodrell Bank, Cheshire, United Kingdom (författare)

VLBI observations of 20 compact quasars have been made between Jodrell Bank and Onsala at a frequency of 1666 MHz. Twelve of the quasars have inverted or peaked spectra at centimetre wavelengths and these are all unresolved, having angular diameters of less than 0.015 arcsec. Two out of five quasars with overall flat spectra are partially resolved on this scale size, as are three steep-spectrum quasars.
