Multifrequency spectral analysis of extragalactic radio sources in the 33-GHz VSA catalogue: sources with flattening and upturn spectrum
We present an analysis of the spectral properties of the extragalactic radio sources in the nearly complete Very Small Array (VSA) sample at 33 GHz. Data from different surveys are used to study source spectra between 1.4 and 33 GHz. We find that, in general, spectra cannot be well described by a single power law in the range of frequencies considered. In particular, most of the VSA sources tha...
متن کاملExploring The Magnetic Field Configuration Close To The Central Engines Using GMVA
The high radio frequency polarization imaging of non-thermal emission from active galactic nuclei (AGN) is a direct way to probe the magnetic field strength and structure in the immediate vicinity of supermassive black holes (SMBHs) and is crucial in testing the jet-launching scenario. To explore the the magnetic field configuration at the base of jets in blazars, we took advantage of the full ...

The complex 10-component gravitational lens B1933+503 has been monitored with the VLA during the period February to June 1998. Here we present the results of this A-configuration 8.4 GHz monitoring campaign. The 37 epochs of observations have an average spacing of 3 days. The data have yielded light curves for the four flat-spectrum radio components (components 1, 3, 4 and 6). We find no signif...
متن کاملEvaluating the deformation monitoring capability of a ground based SAR system with MIMO antenna
By increasing the applicability of ground-based SAR (GBSAR) systems in geoscience and remote sensing, the development and evaluation of new systems have gained attention. GBSAR systems can be utilized for monitoring areas that are hard to or cannot be seen by the airborne or spaceborne systems. Furthermore, they have better spatial and temporal resolutions and are cost-effective and easy to imp...

We monitored 3C 273 with VLBI at 15–86 GHz since 1990. We discuss component trajectories, opacity effects, a rotating jet, and outburst-ejection relations from Gamma-ray to radio bands.
