Characteristics of GPS sources in the Planck survey

Volvach, A. E.; Kardashev, N. S.; Larionov, M. G. +1 more

Two series of 22.2 and 36.8-GHz observations of 43 GHz-Peaked Spectrum (GPS) radio sources from the Planck survey have been carried out using the 22-m radio telescope of the Crimean Astrophysical Observatory in 2014-2015, with the aim of studying the variability of these sources. The interval between the two series of observations was about nine m…

Long-term variability of active galactic nuclei from the "Planck" catalog

Volvach, A. E.; Kardashev, N. S.; Larionov, M. G. +1 more

A complete sample of 104 bright active galactic nuclei (AGNs) from the "Planck" catalog (early results) were observed at 36.8 GHz with the 22-m radio telescope of the Crimean Astrophysical Observatory (CrAO).Variability indices of the sources at this frequency were determined based on data from theWMAP space observatory, theMetsa¨ hovi RadioObserv…
