VLBI observations of nearby radio loud Active Galactic Nuclei
G. Giovannini, E. Liuzzo, M. Giroletti +1
We present an update of the parsec scale properties of the Bologna Complete Sample consisting of 95 radio sources from the B2 Catalog of Radio Sources and the Third Cambridge Revis…
The two sided parsec scale structure of the Low Luminosity Active Galactic Nucleus in NGC 4278
M. Giroletti, G. B. Taylor, G. Giovannini
We present new Very Long Baseline Interferometry observations of the LINER galaxy NGC 4278. The observations were taken with the Very Long Baseline Array (VLBA) and a single antenn…
Magnetic Fields and Faraday Rotation in Clusters of Galaxies
M. Murgia, F. Govoni, L. Feretti +5
We present a numerical approach to investigate the relationship between magnetic fields and Faraday rotation effects in clusters of galaxies. We can infer the structure and strengt…
Magnetic Fields in Clusters of Galaxies Obtained Through the Study of Faraday Rotation Measures
F. Govoni, L. Feretti, M. Murgia +3
We are developing a new approach to investigate cluster magnetic field strengths and structures. It is based on the comparison of simulated Rotation Measure and radio halo images,…
Radio galaxies and magnetic fields in A514
F. Govoni, G. B. Taylor, D. Dallacasa +2
A514 contains six extended and polarized radio sources located at various projected distances from the cluster center. Here we present a detailed study of these six radio sources i…
Restarting activity in radio galaxies
L. Lara, G. Giovannini, W. D. Cotton +5
We present observations of two radio galaxies, J1835+620 and 3C338, both with signs of having passed through different stages of core activity. The former presents two symmetric an…
B2 1144+35: A Giant Low Power Radio Galaxy with Superluminal Motion
G. Giovannini, G. B. Taylor, E. Arbizzani +5
We report on centimeter VLA and VLBI observations of the giant, low power radio galaxy 1144+35. These observations are sensitive to structures on scales from less than 1 parsec to…
