Kinetic or thermal AGN feedback in simulations of isolated and merging disk galaxies calibrated by the M-sigma relation
Paramita Barai, Matteo Viel, Giuseppe Murante +2
(Abridged) We investigate two modes of coupling the feedback energy from a central AGN to the neighboring gas in galaxy simulations: kinetic - velocity boost, and thermal - heating…
Constraining turbulence and conduction in the hot ICM through density perturbations
M. Gaspari, E. Churazov
Using 3D high-resolution hydrodynamic simulations, tracking both electrons and ions, we study the effects of turbulence and conduction in the hot intracluster medium. We show how t…
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: The astrophysics of galaxy groups and clusters
S. Ettori, G. W. Pratt, J. de Plaa +28
As the nodes of the cosmic web, clusters of galaxies trace the large-scale distribution of matter in the Universe. They are thus privileged sites in which to investigate the comple…
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…
Cold fronts and metal anisotropies in the X-ray cool core of the galaxy cluster Zw1742+3306
S. Ettori, F. Gastaldello, M. Gitti +5
(Context) In recent years, our understanding of the cool cores of galaxy clusters has changed. Once thought to be relatively simple places where gas cools and flows toward the cent…
Chaotic cold accretion onto black holes
M. Gaspari, M. Ruszkowski, S. Peng Oh
Using 3D AMR simulations, linking the 50 kpc to the sub-pc scales over the course of 40 Myr, we systematically relax the classic Bondi assumptions in a typical galaxy hosting a SMB…
