Bulk Comptonization spectra in blazars
Annalisa Celotti, Gabriele Ghisellini, Andrew C. Fabian
We study the time dependent spectra produced via the bulk Compton process by a cold, relativistic shell of plasma moving (and accelerating) along the jet of a blazar, scattering on…
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…
Radiative pressure feedback by a quasar in a galactic bulge
A. C. Fabian, A. Celotti, M. C. Erlund
We show that Eddington-limited black hole luminosities can be sufficient to deplete a galaxy bulge of gas through radiation pressure, when the ionization state of the gas and the p…
Have we detected the most luminous ULX so far?
G. Miniutti, G. Ponti, M. Dadina +4
We report the XMM-Newton detection of a moderately bright X-ray source superimposed on the outer arms of the inactive spiral galaxy MCG-03-34-63 (z=0.0213). It is clearly offset fr…
Enrichment in the Centaurus cluster of galaxies
J. S. Sanders, A. C. Fabian
We perform a detailed spatially-resolved, spectroscopic, analysis of the core of the Centaurus cluster of galaxies using a deep Chandra X-ray observation and XMM-Newton data. The C…
