Studying the X-ray hysteresis in GX 339-4: the disc and iron line over one decade
R. J. H. Dunn, R. P. Fender, E. G. Koerding +2
We report on a comprehensive and consistent investigation into the X-ray emission from GX 339-4. All public observations in the 11 year RXTE archive were analysed. Three different…
Investigating Heating and Cooling in the BCS & B55 Cluster Samples
R. J. H. Dunn, A. C. Fabian
We study clusters in the BCS cluster sample which are observed by Chandra and are more distant than redshift, z>0.1. We select from this subsample the clusters which have both a sh…
AGN-Induced Cavities in NGC 1399 and NGC 4649
K. Shurkin, R. J. H. Dunn, G. Gentile +2
We present an analysis of archival Chandra and VLA observations of the E0 galaxy NGC 1399 and the E2 galaxy NGC 4649 in which we investigate cavities in the surrounding X-ray emitt…
Investigating AGN Heating in a Sample of Nearby Clusters
R. J. H. Dunn, A. C. Fabian
We analyse those objects in the Brightest 55 sample of clusters of galaxies which have a short central cooling time and a central temperature drop. Such clusters are likely to requ…
Using Radio Bubbles to Constrain the Matter Content of AGN Jets
R. J. H. Dunn, A. C. Fabian, A. Celotti
We revisit a method to obtain upper limits on the jet matter content combining synchrotron self-absorption constraints and the large scale bubble energy. We use both X-ray observat…
The relation between accretion rate and jet power in X-ray luminous elliptical galaxies
S. W. Allen, R. J. H. Dunn, A. C. Fabian +2
Using Chandra X-ray observations of 9 nearby, X-ray luminous ellipticals with good optical velocity dispersion measurements, we show that a tight correlation exists between the Bon…
