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 ...
An active galactic nucleus driven shock in the intracluster medium around the radio galaxy 3C310
(2012-04-10)
We present results from a 57.6 ks Chandra observation of the cluster gas associated with the fat-double radio galaxy 3C 310. We find a surface brightness discontinuity in the gas outside the southern radio lobe that we ...
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 ...
A flare in the jet of Pictor A
(2010)
A Chandra X-ray imaging observation of the jet in Pictor A showed a feature that appears to be a flare that faded between 2000 and 2002. The feature was not detected in a follow-up observation in 2009. The jet itself is ...
