The spectral variability of the GHz-peaked spectrum radio source PKS 1718-649 and a comparison of absorption models

The spectral variability of the GHz-peaked spectrum radio source PKS 1718-649 and a comparison of absorption models

Using the new wideband capabilities of the ATCA, we obtain spectra for PKS 1718-649, a well-known gigahertzpeaked spectrum radio source. The observations, between approximately 1 and 10 GHz over 3 epochs spanning approximately 21 months, reveal variability both above the spectral peak at ~3 GHz and...
