Opacity in parsec-scale jets of active galactic nuclei: VLBA study from 1.4 to 15 GHz
Y. Y. Kovalev, A. B. Pushkarev, A. P. Lobanov +1
In extragalactic jets, the apparent position of the bright/narrow end (the core) depends on the observing frequency, owing to synchrotron self-absorption and external absorption. T…
Parsec-scale properties of GHz-Peaked Spectrum sources from 2.3 and 8.6 GHz VLBI surveys
K. V. Sokolovsky, Y. Y. Kovalev
We investigate the sample of 213 GPS sources selected from simultaneous multi-frequency 1-22 GHz observations obtained with RATAN-600 radio telescope. We use publicly available dat…
A sample of GHz-peaked spectrum sources selected at RATAN-600: spectral and variability properties
K. V. Sokolovsky, Y. Y. Kovalev, Yu. A. Kovalev +2
We describe a new sample of 226 GPS (GHz-Peaked Spectrum) source candidates selected using simultaneous 1-22 GHz multi-frequency observations with the RATAN-600 radio telescope. Si…
