Active galactic nucleus jet feedback in hydrostatic halos
Rainer Weinberger, Kung-Yi Su, Kristian Ehlert +8
Feedback driven by jets from active galactic nuclei is believed to be responsible for reducing cooling flows in cool-core galaxy clusters. We use simulations to model feedback from…
Self-regulated AGN feedback of light jets in cool-core galaxy clusters
Kristian Ehlert, Rainer Weinberger, Christoph Pfrommer +2
Heating from active galactic nuclei (AGN) is thought to stabilize cool-core clusters, limiting star formation and cooling flows. We employ radiative magneto-hydrodynamic (MHD) simu…
Turning AGN bubbles into radio relics with sloshing: modeling CR transport with realistic physics
John ZuHone, Kristian Ehlert, Rainer Weinberger +1
Radio relics are arc-like synchrotron sources at the periphery of galaxy clusters, produced by cosmic-ray electrons in a G magnetic field which are believed to have been (re-)ac…
How merger-driven gas motions in galaxy clusters can turn AGN bubbles into radio relics
John A. ZuHone, Maxim Markevitch, Rainer Weinberger +2
Radio relics in galaxy clusters are extended synchrotron sources produced by cosmic-ray electrons in the G magnetic field. Many relics are found in the cluster periphery and hav…
Connecting turbulent velocities and magnetic fields in galaxy cluster simulations with active galactic nuclei jets
Kristian Ehlert, Rainer Weinberger, Christoph Pfrommer +1
The study of velocity fields of the hot gas in galaxy clusters can help to unravel details of microphysics on small-scales and to decipher the nature of feedback by active galactic…
Interaction of a cold cloud with a hot wind: the regimes of cloud growth and destruction and the impact of magnetic fields
Martin Sparre, Christoph Pfrommer, Kristian Ehlert
Multiphase galaxy winds, the accretion of cold gas through galaxy haloes, and gas stripping from jellyfish galaxies are examples of interactions between cold and hot gaseous phases…
The Sunyaev-Zel'dovich effect of simulated jet-inflated bubbles in clusters
Kristian Ehlert, Christoph Pfrommer, Rainer Weinberger +2
Feedback by active galactic nuclei (AGNs) is essential for regulating the fast radiative cooling of low-entropy gas at the centers of galaxy clusters and for reducing star formatio…
Simulations of the dynamics of magnetised jets and cosmic rays in galaxy clusters
Kristian Ehlert, Rainer Weinberger, Christoph Pfrommer +2
Feedback processes by active galactic nuclei in the centres of galaxy clusters appear to prevent large-scale cooling flows and impede star formation. However, the detailed heating…
Constraining the coherence scale of the interstellar magnetic field using TeV gamma-ray observations of supernova remnants
Matteo Pais, Christoph Pfrommer, Kristian Ehlert +2
Galactic cosmic rays (CRs) are believed to be accelerated at supernova remnant (SNR) shocks. In the hadronic scenario the TeV gamma-ray emission from SNRs originates from decaying…
The effect of cosmic-ray acceleration on supernova blast wave dynamics
M. Pais, C. Pfrommer, K. Ehlert +1
Non-relativistic shocks accelerate ions to highly relativistic energies provided that the orientation of the magnetic field is closely aligned with the shock normal (quasi-parallel…
Simulating the interaction of jets with the intra-cluster medium
Rainer Weinberger, Kristian Ehlert, Christoph Pfrommer +2
Jets from supermassive black holes in the centres of galaxy clusters are a potential candidate for moderating gas cooling and subsequent star formation through depositing energy in…
