Astronomy and Astrophysics Iii Zw 2, the First Superluminal Jet in a Seyfert Galaxy
So far all relativistically boosted jets with superluminal motion have only been detected in typical radio galaxies with early type host galaxies. We have now discovered superluminal motion in the Seyfert I galaxy III Zw 2, classified as a spiral. Superluminal motion was first inferred from the spectral evolution of the source and then confirmed by VLBI observations. The lower limit for the app...

متن کاملA major radio outburst in III Zw 2 with an extremely inverted ,
III Zw 2 is a spiral galaxy with an optical spectrum and faint extended radio structure typical of a Seyfert galaxy, but also with an extremely variable, blazar-like radio core. We have now discovered a new radio are where the source has brightened more than twenty-fold within less than two years. A broad-band radio spectrum between 1.4 and 666 GHz shows a textbook-like synchrotron spectrum pea...
متن کاملEvolution in a nutshell
The European Molecular Biology Laboratory in Heidelberg hosted an exciting 2-day symposium last November covering various topics of evolution. The symposium was unusual in two respects: first, it had been organised entirely by PhD students; secondly, the invited speakers had been encouraged not only to talk about their most recent work, but also to present a general overview of their field of s...
متن کاملEvolution of a radio jet in a Seyfert galaxy
A very detailed monitoring of a radio flare in the Seyfert I galaxy III Zw 2 with the VLA and the VLBA is presented. The relative astrometry in the VLBA observations was precise on a level of a few μas. Spectral and spatial evolution of the source are closely linked and these observations allowed us to study in great detail a textbook example of a synchrotron self-absorbed jet. We observe a pha...
