VLBI observations of Brightest Cluster Galaxies: are cooling and parsec scale morphology correlated?

E. Liuzzo, G. Giovannini, M. Giroletti

We present a statistical study on parsec scale properties of a sample of Brigthest Cluster Galaxies (BCGs) in Abell Clusters. These data show a possible difference between BCGs in…

The Evolution of AGN in Groups and Clusters

Paul Martini

The evolution of AGN in groups and clusters provides important information about how their black holes grow, the extent to which galaxies and black holes coevolve in dense environm…

The big picture of AGN feedback: Black hole accretion and galaxy evolution in multiwavelength surveys

Ryan C. Hickox

Large extragalactic surveys allow us to trace, in a statistical sense, how supermassive black holes, their host galaxies, and their dark matter halos evolve together over cosmic ti…

X-raying the Winds of Luminous Active Galaxies

W. N. Brandt, G. Chartas, S. C. Gallagher +2

We briefly describe some recent observational results, mainly at X-ray wavelengths, on the winds of luminous active galactic nuclei (AGNs). These winds likely play a significant ro…

Combining Semi-Analytic Models of Galaxy Formation with Simulations of Galaxy Clusters: the Need for AGN Heating

C. J. Short, P. A. Thomas

We present hydrodynamical N-body simulations of clusters of galaxies with feedback taken from semi-analytic models of galaxy formation. The advantage of this technique is that the…

The Detectability of AGN Cavities in Cooling-Flow Clusters

L. Birzan, D. A. Rafferty, B. R. McNamara +2

Chandra X-ray Observatory has revealed X-ray cavities in many nearby cooling flow clusters. The cavities trace feedback from the central active galactic nulceus (AGN) on the intrac…
