The active nuclei of z < 1.0 3CRR radio sources
(2009)
We combine Chandra and XMM–Newton X-ray data from our previous papers with new X-ray observations and with Spitzer mid-infrared (mid-IR) data in order to study the nature of the nuclei of radio galaxies and radio-loud ...
Luminosity functions of LMXBs in Centaurus A: globular clusters versus the field
(2009)
We study the X-ray luminosity function (XLF) of low-mass X-ray binaries (LMXB) in the nearby early-type galaxy Centaurus A, concentrating primarily on two aspects of binary populations: the XLF behavior at the low-luminosity ...
High-energy particle acceleration at the radio-lobe shock of Centaurus A
(2009)
We present new results on the shock around the south-west radio lobe of Centaurus A using data from the Chandra Very Large Programme observations (740 ks total observing time). The X-ray spectrum of the emission around the ...
Where Centaurus A gets its X-ray knottiness
(2008)
We report an X-ray spectral study of the transverse structure of the Centaurus A jet using new data from the Chandra Cen A Very Large Project. We find that the spectrum steepens with increasing distance from the jet axis, ...
Evidence for Non-Hydrostatic Gas Motions in the Hot Interstellar Medium of Centaurus A
(2008)
We present preliminary results from a deep (600 ks) Chandra observation of the hot interstellar medium of the nearby early-type galaxy Centaurus A. We find a surface brightness discontinuity in the gas ~3.5 kpc from the ...
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 ...
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 ...
