Parsec--scale radio jets in gamma--ray loud sources
T. Venturi, D. Dallacasa
We will present a multiepoch study of the three blazars 0954+658 (BL--Lac), PKS1510--089 (HPQ) and 1749+096 (BL--Lac). The first two sources are known to be --ray loud. Our stud…
Lobe Advance Velocities in the Extragalactic Compact Symmetric Object 4C 31.04
M. Giroletti, G. Giovannini, G. B. Taylor +3
We report on the results of a two epoch study of the low power Compact Symmetric Object 4C 31.04. Observations performed with the VLBA at 5 GHz in 1995 and 2000 have yielded images…
Parsec Scale Properties of Radio Sources
G. Giovannini, M. Giroletti, G. B. Taylor +3
We present a new complete sample of radio sources selected from the B2 and 3CR catalogues, with no bias respect to the jet velocity and orientation. Using preliminary data we inves…
Abell 3560, a galaxy cluster at the edge of a major merging event
S. Bardelli, T. Venturi, E. Zucca +3
In this paper we study A3560, a rich cluster at the southern periphery of the A3558 complex, a chain of interacting clusters in the central part of the Shapley Concentration superc…
Optical and Radio monitoring of S5 1803+74
R. Nesci, E. Massaro, M. Maesano +5
The optical (BVRI) and radio (8.4 GHz) light curves of S5 1803+784 on a time span of nearly 6 years are presented and discussed. The optical light curve showed an overall variation…
Radio emission from the A3571 cluster complex: the final stage of a cluster merger?
T. Venturi, S. Bardelli, M. Zagaria +2
In this paper we report and discuss the results of a radio survey in the A3571 cluster complex, a structure located in the Shapley Concentration core, and formed by the three clust…
