High-energy Particle Acceleration and Production of Ultra-high-energy Cosmic Rays in the Giant Lobes of Centaurus A
(2009)
The nearby radio galaxy Centaurus A is poorly studied at high frequencies with conventional radio telescopes because of its very large angular size, but is one of a very few extragalactic objects to be detected and resolved ...
Radio Galaxy Physics at Low Frequencies: Lobes, Jets and Environments
(Astronomical Society of the Pacific, 2009)
I discuss the key role of low-frequency observations in determining the physical properties of radio galaxies and radio-loud quasars, and their application in studies of the interaction between radio sources and their ...
The dynamics of the giant radio galaxy 3C 457
(2009)
We present multifrequency radio observations with the Giant Metrewave Radio Telescope and Very Large Array, and X-ray observations with the X-ray Multi-Mirror Mission (XMM–Newton) telescope of the giant radio source (GRS) ...
Bayesian inference of jet bulk-flow speeds in Fanaroff–Riley type II radio sources
(2009)
Radio jet and core data for a complete sample of 98 Fanaroff–Riley type II sources with z < 1 are analysed with a Markov Chain Monte Carlo model fitting method to obtain constraints on bulk-flow speeds in the beam. The ...
The jet heated x-ray filament in the Centaurus A northern middle radio lobe
(2009)
We present results from a 40 ks XMM-Newton observation of the X-ray filament coincident with the southeast edge of the Centaurus A Northern Middle Radio Lobe (NML). We find that the X-ray filament consists of five spatially ...
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 ...
