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…
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…
Precession of the Super-Massive Black Hole in NGC 1275 (3C 84)?
R. J. H. Dunn, A. C. Fabian, J. S. Sanders
The X-ray holes at the centre of the Perseus Cluster of galaxies are not all at the same position angle with respect to the centre of the cluster. This configuration would result i…
Non-thermal X-rays, a high abundance ridge and fossil bubbles in the core of the Perseus cluster of galaxies
J. S. Sanders, A. C. Fabian, R. J. H. Dunn
Using a deep Chandra observation of the Perseus cluster of galaxies, we find a high-abundance shell 250 arcsec (93 kpc) from the central nucleus. This ridge lies at the edge of the…
