Where Centaurus A gets its X-ray knottiness
D. M. Worrall, M. Birkinshaw, R. P. Kraft +15
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 wi…
The nature of the ghost cavity in the NGC 741 group
Nazirah N. Jetha, Martin J. Hardcastle, Arif Babul +4
We discuss the effects of energy injection into the intra-group medium of the group of galaxies associated with NGC 741. The X-ray emission reveals a large bubble, which in the abs…
Low-Mass X-ray Binaries and Globular Clusters in Centaurus A
Andres Jordan, Gregory R. Sivakoff, Dean E. McLaughlin +19
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 Cen…
New results on particle acceleration in the Centaurus A jet and counterjet from a deep Chandra observation
M. J. Hardcastle, R. P. Kraft, G. R. Sivakoff +16
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…
High redshift FRII radio sources: large-scale X-ray environment
Elena Belsole, Diana M. Worrall, Martin J. Hardcastle +1
We investigate the properties of the environment around 20 powerful radio galaxies and quasars at redshifts between 0.45 and 1. Using XMM-Newton and Chandra observations we probe t…
3C 40 in Abell 194: can tail radio galaxies exist in a quiescent cluster?
I. Sakelliou, M. J. Hardcastle, N. N. Jetha
The nearby cluster Abell 194 hosts two luminous, distorted radio galaxies. Both reside within the cluster's core region, being separated in projection by only 100 kpc. It is often…
