Adiabatic expansion and magnetic fields in AGN jets
A. B. Pushkarev, Y. Y. Kovalev, A. P. Lobanov
Results of high-resolution simultaneous multi-frequency 8.1-15.4 GHz VLBA polarimetric observations of relativistic jets in active galactic nuclei (the MOJAVE-2 project) are analyz…
Probing parsec scale jets in AGN with geodetic VLBI
A. B. Pushkarev, Y. Y. Kovalev
We report on an ongoing effort to image active galactic nuclei simultaneously observed at 2.3 and 8.6 GHz in the framework of a long-term VLBI project RDV (Research and Development…
15 GHz VLBI detection of the HST-1 feature in the M87 jet
C. S. Chang, E. Ros, Y. Y. Kovalev +1
A bright feature 100 pc away from the core in the powerful jet of M 87 shows mysterious properties. Earlier radio, optical and X-ray observations have shown that this feature, labe…
High-resolution studies of the twin jet in NGC 1052
E. Ros, M. Kadler, Y. Y. Kovalev +3
The radio loud galaxy NGC 1052 is being studied in an intensive multi-band campaign including X-ray brigthness monitoring and spectroscopic observations, single-dish radio brightne…
Physics of the central region in the quasar 0850+581
Y. Y. Kovalev, A. P. Lobanov, A. B. Pushkarev
The apparent position of the origin (core) of extragalactic radio jets shifts with the observing frequency, owing to synchrotron self-absorption and external absorption. One of the…
Testing adiabatic expansion of shocks in parsec-scale jets by dual-frequency VLBI experiments
A. B. Pushkarev, Y. Y. Kovalev, A. P. Lobanov
We present results of simultaneous dual-frequency (2 GHz and 8 GHz) very long baseline interferometry (VLBI) observations of 12 active galactic nuclei with prominent jets. Spectral…
