Spectral properties of X-ray binaries in Centaurus A
(2013-04-01)
We present a spectral investigation of X-ray binaries (XBs) in NGC 5128 (Cen A), using six 100 ks Chandra observations taken over two months in 2007. We divide our sample into thermally and non-thermally dominated states ...
A transient sub-Eddington black hole X-ray binary candidate in the dust lanes of Centaurus A
(2012-04-20)
We report the discovery of a bright X-ray transient CXOU J132527.6-430023 in the nearby early-type galaxy NGC5128. The source was first detected over the course of five Chandra observations in 2007, reaching an unabsorbed ...
Long-term monitoring of the dynamics and particle acceleration of knots in the jet of Centaurus A
(2010)
We present new and archival multi-frequency radio and X-ray data for Centaurus A obtained over almost 20 years at the Very Large Array and with Chandra, with which we measure the X-ray and radio spectral indices of jet ...
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 ...
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 ...
New results on particle acceleration in the Centaurus A jet and counterjet from a deep Chandra observation
(2007)
We present new deep Chandra observations of the Centaurus A jet, with a combined on-source exposure time of 719 ks. These data allow detailed X-ray spectral measurements to be made along the jet out to its disappearance ...
