Equipartition in the hot-spots of 3C 123
(Astronomical Society of the Pacific, 2001)
Chandra X-ray Observatory observations of the powerful, peculiar radio galaxy 3C 123 have resulted in an X-ray detection of the bright eastern hot-spot, with a 1-ke V flux density of ~5 nJy. The X-ray flux and spectrum of ...
The infrared jet in 3C 66B
(2000)
Radio, optical and X-ray nuclei in nearby 3CRR radio galaxies
(2000)
HST observations have shown that low-redshift 3CR radio galaxies often exhibit a point-like optical component positionally coincident with the GHz-frequency radio core. In this paper we discuss the correlation between the ...
The environments of FRII radio sources
(2000)
Using ROSAT observations, we estimate gas pressures in the X-ray-emitting medium surrounding 63 FRII radio galaxies and quasars. We compare these pressures with the internal pressures of the radio-emitting plasma estimated ...
Determining the reality of x-ray filaments
(2000)
A number of authors have reported filaments connecting bright structures in high-resolution X-ray images, and in some cases these have been taken as evidence for a physical connection between the structures, which might ...
X-ray observations of low-power radio galaxies from the B2 catalogue
(1999)
We present an analysis of X-ray data, taken with ROSAT, for a well defined sample of low-power radio galaxies from the Bologna B2 catalogue. Where possible, the HRI has been used in order to take advantage of the higher ...
FR II radio galaxies with z<0.3 -- II. Beaming and unification
(1999)
In a previous paper we presented measurements of the properties of jets and cores in a large sample of FRII radio galaxies with z < 0.3. Here we test, by means of Monte Carlo simulations, the consistency of those data with ...
Extended X-ray emission from the BL Lac object PKS 0521-365
(1999)
Models that seek to unify BL Lacs and low-power radio galaxies predict that the two types of object should show similar isotropically emitted X-ray emission. Testing this is usually limited by difficulties in separating ...
The complex radio spectrum of 3C130
(1999)
I present four-frequency radio observations of the wide-angle tail radio galaxy 3C130. By a technique of simulated observations, I assess the systematic errors in the data due to the varying uv plane coverage in the different ...
ROSAT X-ray observations of 3CRR radio sources
(1999)
Over half the 3CRR sample of radio galaxies and quasars has been observed in X-rays with ROSAT pointed observations, and we present results from these observations, discussing many of the sources in detail. The improved ...
