L. Feretti, R. Perley, G. Giovannini +1
In this paper we present multifrequency VLA observations of the giant radio galaxy 3C 449, obtained with high sensitivity and resolution in total intensity and polarized flux. Thes…
The REX survey: a search for Radio Emitting X-ray sources
A. Caccianiga, T. Maccacaro, A. Wolter +2
We present the scientific goals, the strategy and the first results of the REX project, an effort aimed at creating a sizable and statistically complete sample of Radio Emitting X-…
Dust in 3C324
P. N. Best, H. J. A. R"ottgering, M. N. Bremer +6
The results of a deep submillimetre observation using SCUBA of the powerful radio galaxy 3C324, at redshift z=1.206, are presented. At 850 microns, emission from the location of th…
Evidence for inverse Compton emission in the powerful radio galaxy 3C 219
G. Brunetti, A. Comastri, G. Setti +1
Spectral analysis of ROSAT PSPC and ASCA archive data and a recent ROSAT HRI observation of the powerful FRII radio galaxy 3C 219 reveal an absorbed point-like source, coincident w…
Space VLBI Observations of MKN501
G. Giovannini, W. D. Cotton, L. Feretti +2
We present here two epochs of Space VLBI Observations at 18 cm of the BL-Lac type object MKN 501. Thanks to the high resolution of these new data, we have found that the inner jet…
IRAS 23385+6053: A Prototype Massive Class 0 Object
Sergio Molinari, Leonardo Testi, Jan Brand +2
IRAS 23385+6053 is a Young Stellar Object with luminosity 16,000 solar luminosities at a kinematic distance of 4.9 kpc. This candidate precursor of an ultracompact HII region is as…
The nature of the optical---radio correlations for powerful radio galaxies
C. N. Tadhunter, R. Morganti, A. Robinson +3
The nature of the optical--radio correlations for powerful radio galaxies is investigated using spectroscopic observations of a complete sample of southern 2Jy radio sources. In li…
