Constraints on the Accretion Region in NGC 1275 from VLBA Observations of the Counterjetfar side jets are similar. This was interpreted as the result of free-free absorption in an ionized medium that lies in front of the counterjet but not in front of the near-side jet. An accretion disk or torus has an appropriate geometry to show this effect (for an analysis, see Levinson .., 1995).

The Environment of OJ 287: Nearby Galaxies and a Long Optical Jet?econd seeing conditions from the whole 1 Jy sample (Stickel et al. 1991) of BL Lac objects. The aims of this study are: 1. to search for very close companions to the BL Lacs, 2. to study the large scale galaxy clustering around the BL Lacs and 3. to study the BL Lac hosts themselves.

The study of local disturbances was of primary importance in the rapid development of radio communications which had been geared by the Marconi’s discovery.

https://doi.org/10.1007/978-3-642-80583-7 was made with the VLBA. The dual-frequency observations identify the core of the radio source, while the multi-epoch observations show the complex structural evolution at a resolution of 0.1 pc. Subluminal motion of ≈ 0.15c is evident. Structural changes are observed on time scales shorter than four months.
