AGN pairs: chance superpositions or black hole binaries?
M. Dotti, M. Ruszkowski
Several active galactic nuclei (AGN) with multiple sets of emission lines separated by over 2000 km/s have been observed recently. These have been interpreted as being due to massi…
Shaken and stirred: conduction and turbulence in clusters of galaxies
M. Ruszkowski, S. Peng Oh
(abridged) Uninhibited radiative cooling in clusters of galaxies would lead to excessive mass accretion rates contrary to observations. One of the key proposals to offset radiative…
AGN Feedback and Bimodality in Cluster Core Entropy
Fulai Guo, S. Peng Oh, M. Ruszkowski
We investigate a series of steady-state models of galaxy clusters, in which the hot intracluster gas is efficiently heated by active galactic nucleus (AGN) feedback and thermal con…
Dual black holes in merger remnants. II: spin evolution and gravitational recoil
M. Dotti, M. Volonteri, A. Perego +3
Using high resolution hydrodynamical simulations, we explore the spin evolution of massive dual black holes orbiting inside a circumnuclear disc, relic of a gas-rich galaxy merger.…
The Evolution of Galaxy Clusters Across Cosmic Time
M. Arnaud, H. Bohringer, C. Jones +40
The large scale structure of the present Universe is determined by the growth of dark matter density fluctuations and by the dynamical action of dark energy and dark matter. While…
The role of dry mergers for the formation and evolution of brightest cluster galaxies
Mateusz Ruszkowski, Volker Springel
Using a resimulation technique, we perform high-resolution cosmological simulations of dry mergers in a massive galaxy cluster identified in the Millennium Run. Our initial conditi…
