Magnetic Field Structure in the Parsec Scale Jet of 3C273 from Multifrequency VLBA Observations
T. Savolainen, K. Wiik, E. Valtaoja +1
We present first results from a multifrequency VLBA observations of 3C273 in 2003. The source was observed simultaneously at 5.0, 8.4, 15.3, 22.2, 43.2 and 86.2 GHz, and from this…
Synchrotron flaring behaviour of CygnusX-3 during the February-March 1994 and September 2001 outbursts
E. J. Lindfors, M. Türler, D. C. Hannikainen +4
Aims: In this paper we study whether the shock-in-jet model, widely used to explain the outbursting behaviour of quasars, can be used to explain the radio flaring behaviour of the…
Statistical analyses of long-term variability of AGN at high radio frequencies
T. Hovatta, M. Tornikoski, M. Lainela +5
We present a study of variability time scales in a large sample of Active Galactic Nuclei at several frequencies between 4.8 and 230 GHz. We investigate the differences of various…
