X-Ray Nuclei in Radio Galaxies: Exploring the Roles of Hot and Cold Gas Accretion
(Astronomical Society of the Pacific, 2008)
We present results from Chandra and XMM-Newton spectroscopic observations of the nuclei of z < 0.5 radio galaxies and quasars from the 3CRR catalog, and examine in detail the dichotomy in the properties of low- and ...
A Transient Black-Hole Low-Mass X-Ray Binary Candidate in Centaurus A
(2008)
We report the discovery of a bright transient X-ray source, CXOU J132518.2–430304, toward Centaurus A (Cen A) using six new Chandra X-Ray Observatory observations in 2007 March-May. Between 2003 and 2007, its flux has ...
XMM-Newton Observations of the Nuclei of the Radio Galaxies 3C 305, DA 240, and 4C 73.08
(2008)
We present new XMM-Newton EPIC observations of the nuclei of the nearby radio galaxies 3C 305, DA 240, and 4C 73.08, and investigate the origin of their nuclear X-ray emission. The nuclei of the three sources appear to ...
Inverse-Compton emission from the lobes of 3C 353
(2008)
X-ray emission due to inverse-Compton scattering of microwave background photons by electrons in the lobes of powerful radio galaxies has now been seen in a large number of objects. Combining an inverse-Compton model for ...
Deep Chandra Observations of the Centaurus A Jet
(Astronomical Society of the Pacific, 2008)
Chandra has observed the jet of Centaurus A for 560 ks in 2007, giving a total on-source observation time since the launch of Chandra of 720 ks. Combining these datasets gives us a uniquely detailed X-ray view of the jet ...
Shock heating by nearby AGN.
(ESO / Springer, 2007)
Hot and cold gas accretion and feedback in radio-loud active galaxies
(2007)
We have recently shown that X-ray observations of the population of ‘low-excitation’ radio galaxies, which includesmost low-power, Fanaroff-Riley class I sources as well as some more powerful Fanaroff-Riley class II objects, ...
