High Galactic latitude polarized emission at 1.4 GHz and implications for cosmic microwave background observations
E. Carretti, G. Bernardi, R. J. Sault +2
We analyse the polarized emission at 1.4 GHz in a 3x3 deg^2 area at high Galactic latitude (b ~ -40deg). The region, centred in (RA=5h, Dec=-49deg), was observed with the Australia…
The two sided parsec scale structure of the Low Luminosity Active Galactic Nucleus in NGC 4278
G. Giovannini, M. Giroletti, G. B. Taylor
We present new Very Long Baseline Interferometry observations of the LINER galaxy NGC 4278 with a linear resolution of < 0.1 pc. Our radio data reveal a two sided structure, with s…
Particle acceleration and non-thermal emission from galaxy clusters
Gianfranco Brunetti
The existence and extent of non-thermal phenomena in galaxy clusters is now well established. A key question in our understanding of these phenomena is the origin of the relativist…
The radio counter-jet of the QSO 3C~48
W. X. Feng, T. An, X. Y. Hong +4
We present multi--frequency radio observational results of the quasar 3C~48. The observations were carried out with the Very Large Array (VLA) at five frequencies of 0.33, 1.5, 4.8…
Cluster mergers and non-thermal phenomena: expectations from a statistical magneto-turbulent model
R. Cassano, G. Brunetti
The most important evidences for non-thermal phenomena in galaxy clusters comes from the spectacular synchrotron radio emission diffused over Mpc scale observed in a growing number…
EVN Observations of the BL Lac object ON 231
F. Mantovani, E. Massaro, R. Fanti +3
New EVN images at 5.0 GHz and 8.4 GHz of ON 231 confirm the complex structure of the source, the identification of the core, the presence of components on the two sides of the core…
Occurence and Luminosity Functions of Giant Radio Halos from Magneto-Turbulent Model
Rossella Cassano, Gianfranco Brunetti, Giancarlo Setti
We calculate the probability to form giant radio halos (~ 1 Mpc size) as a function of the mass of the host clusters by using a Statistical Magneto-Turbulent Model (Cassano & Brune…
Polarization in CSS/GPS radio sources
D. Dallacasa
The polarisation properties of the intrinsically small (< 20 kpc) radio sources are briefly discussed. At centimetric and decimetric wavelengths, substantial polarised emission is…
Optical and Radio emission from BL Lac objects: long-term trends and structural changes
E. Massaro, F. Mantovani
Optical light curves of bright BL Lac objects, in particular those having the SED synchrotron peak at frequencies lower than 10E14 Hz, are characterized by long-term trends with ti…
