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 ...
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 ...
Cen A and its Interaction with the X-ray Emitting Interstellar Medium
(2004)
As the closest radio galaxy, Centaurus A is a powerful laboratory for the X-ray study of radio-emitting structures and their interactions with the hot interstellar medium (ISM). This paper details our interpretation of the ...
The Jet/ISM Interaction in Three Nearby Radio Galaxies as Seen with Chandra.
(2004)
Chandra observations of radio galaxies have demonstrated a wide range of complex interactions between their jets and the ambient interstellar/intracluster medium (ISM/ICM). In this paper, we discuss results from Chandra ...
Radio and X-Ray Observations of the Jet in Centaurus A
(2003-08)
We present new, high dynamic range VLA images of the inner jet of the closest radio galaxy, Centaurus A. Over a 10 yr baseline we detect apparent subluminal motions (v ~ 0:5c) in the jet on scales of hundreds of parsecs. ...
High resolution X-ray observation and monitoring of the x-ray jet and radio lobes of Centaurus A
(2003)
We summarize the results of our Chandra AO-1 observations of the X-ray jet in the nearby radio galaxy Centaurus A, and discuss preliminary results from our ongoing monitoring campaign, the first observation of which was ...
Chandra Observations of the X-Ray Jet in Centaurus A
(2002-04)
We present high angular resolution X-ray images and spectra from two Chandra AXAF CCD Imaging Spectrometer (ACIS-I) observations of the X-ray jet in the nearby radio galaxy Cen A. We find that the X-ray emission from the ...
