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, ...
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 ...
Low-Mass X-ray Binaries and Globular Clusters in Centaurus A
(2007)
We present results of Hubble Space Telescope and Chandra X-Ray Observatory observations of globular clusters (GCs) and low-mass X-ray binaries (LMXBs) in the central regions of Centaurus A. Out of 440 GC candidates, we ...
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 ...
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 ...
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 ...
