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…

The Apparent "Angular Size - Frequency" Dependence in ~3000 Parsec-scale Extragalactic Jets

J. Yang, L. I. Gurvits, S. Frey +1

The upper envelope of the amplitude of the VLBI visibility function usually represents the most compact structural pattern of extragalactic radio sources, in particular, the "core-…

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…

Array configuration studies for the SKA -- Implementation of figures of merit based on SDR

Dharam V. Lal, Andrei P. Lobanov

The Square Kilometre Array is going to become operational at the time when several new large optical, X-ray and Gamma-ray telescopes are expected to be working. The main drive for…

GMRT study of X-shaped radio sources

Dharam Vir Lal, A. Pramesh Rao, Martin J. Hardcastle +5

Context. The nature of X-shaped sources is a matter of considerable debate in the literature: it has even been proposed that they provide evidence for black-hole-mergers/spin-reori…

Jet-BLR connection in the radio galaxy 3C 390.3

T. G. Arshakian, J. Leon-Tavares, A. P. Lobanov +5

Variations of the optical continuum emission in the radio galaxy 3C 390.3 are compared to the properties of radio emission from the compact, sub-parsec-scale jet in this object. We…
