An all-sky optical catalogue of radio/X-ray sources
(2004-11)
We present an all-sky catalogue that aligns and overlays the ROSAT HRI, RASS, PSPC and WGA X-ray catalogues and the NVSS, FIRST and SUMSS radio catalogues onto the optical APM and USNO-A catalogues. Objects presented are ...
Chandra and XMM-Newton Observations of the Nucleus of Centaurus A
(2004-09)
We present X-ray spectra of the nucleus of the nearby radio galaxy Centaurus A from observations with the XMM-Newton EPIC CCD cameras (two exposures separated by 12 months) and the Chandra HETGS. For the first time in an ...
Particle acceleration and jet dynamics in Centaurus A
(2004-06)
New multi-epoch Chandra observations, combined with multi-epoch, high-dynamic range VLA data, have allowed us to relate the radio and X-ray structure of the jet in Cen A to the jet dynamics. We present evidence that a ...
Bgg revisited: The environments of low-excitation radio galaxies and unified models
(2004-02)
Recent measurements of the galaxy clustering environments around intermediate-redshift radio sources have suggested a systematic environmental difference between radio galaxies and radio-loud quasars, in contradiction to ...
Jet/Environment Interactions of FRI and FRII Radio Galaxies.
(2004)
We present the results of new XMM-Newton observations of FRI and FRII radio galaxies that show the importance of jet/environment interactions for both radiosource structure and the properties of the surrounding gas. The ...
