Tracing the evolution of Active Galactic Nuclei host galaxies over the last 9 Gyrs of Cosmic time
Andy D. Goulding, William R. Forman, Ryan C. Hickox +11
We present the results of a combined galaxy population analysis for the host galaxies of active galactic nuclei (AGN) identified at 0 < z < 1.4 within the SDSS, Bootes and DEEP2 su…
The fading of two transient ULXs to below the stellar mass Eddington limit
Mark J. Burke, Ralph P. Kraft, Roberto Soria +10
We report new detections of the two transient ultraluminous X-ray sources (ULXs) in NGC 5128 from an ongoing series of Chandra observations. Both sources have previously been obser…
Deep Chandra Observations of Abell 2199: the Interplay between Merger-Induced Gas Motions and Nuclear Outbursts in a Cool Core Cluster
Paul E. J. Nulsen, Zhiyuan Li, William R. Forman +9
We present new Chandra observations of Abell 2199 that show evidence of gas sloshing due to a minor merger, as well as impacts of the radio source, 3C 338, hosted by the central ga…
The Hot and Energetic Universe: AGN feedback in galaxy clusters and groups
J. H. Croston, J. S. Sanders, S. Heinz +25
Mechanical feedback via Active Galactic Nuclei (AGN) jets in the centres of galaxy groups and clusters is a crucial ingredient in current models of galaxy formation and cluster evo…
The Hot and Energetic Universe: A White Paper presenting the science theme motivating the Athena+ mission
Kirpal Nandra, Didier Barret, Xavier Barcons +237
This White Paper, submitted to the recent ESA call for science themes to define its future large missions, advocates the need for a transformational leap in our understanding of tw…
Detection of a luminous hot X-ray corona around the massive spiral galaxy NGC266
Akos Bogdan, William R. Forman, Ralph P. Kraft +1
The presence of luminous hot X-ray coronae in the dark matter halos of massive spiral galaxies is a basic prediction of galaxy formation models. However, observational evidence for…
