AGN Outflow Shocks on Bonnor-Ebert Spheres
Zachary Dugan, Volker Gaibler, Rebekka Bieri +2
Feedback from Active Galactic Nuclei (AGN) and subsequent jet cocoons and outflow bubbles can have a significant impact on star formation in the host galaxy. To investigate feedbac…
Feedback by AGN Jets and Wide-Angle Winds on a Galactic Scale
Zachary Dugan, Volker Gaibler, Joseph Silk
To investigate the differences in mechanical feedback from radio-loud and radio-quiet Active Galactic Nuclei (AGN) on the host galaxy, we perform 3D AMR hydrodynamic simulations of…
External pressure-triggering of star formation in a disc galaxy: a template for positive feedback
Rebekka Bieri, Yohan Dubois, Joseph Silk +2
Feedback from active galactic nuclei (AGN) has often been invoked both in simulations and in interpreting observations for regulating star formation and quenching cooling flows in…
Asymmetries of AGN jets in inhomogeneous media
Volker Gaibler
Considerable asymmetries in jets from active galactic nuclei (AGN) and associated double radio sources can be caused by an inhomogeneous interstellar medium of the host galaxy. The…
Positive and negative feedback by AGN jets in high-redshift galaxies
V. Gaibler
Simulations of feedback by jets from active galactic nuclei (AGN) in the past mostly focused on the interaction at large scales as the circumgalactic medium or intra-cluster medium…
Stellar Signatures of AGN Jet Triggered Star Formation
Zachary Dugan, Sarah Bryan, Volker Gaibler +2
To investigate feedback between relativistic jets emanating from Active Galactic Nuclei (AGN) and the stellar population of the host galaxy, we analyze the long-term evolution of t…
Jet interactions with a giant molecular cloud in the Galactic centre and ejection of hypervelocity stars
Joseph Silk, Vincenzo Antonuccio-Delogu, Yohan Dubois +4
The hypervelocity OB stars in the Milky Way Galaxy were ejected from the central regions some 10-100 million years ago. We argue that these stars, {as well as many more abundant bo…
Jet-induced star formation in gas-rich galaxies
Volker Gaibler, Sadegh Khochfar, Martin Krause +1
Feedback from active galactic nuclei (AGN) has become a major component in simulations of galaxy evolution, in particular for massive galaxies. AGN jets have been shown to provide…
Asymmetries in Extragalactic Double Radio Sources: Clues from 3D Simulations of Jet - Disc Interaction
Volker Gaibler, Sadegh Khochfar, Martin Krause
Observational and theoretical studies of extragalactic radio sources have suggested that an inhomogeneous environment may be responsible for observed arm length asymmetries of jets…
Physics and fate of jet related emission line regions
Martin Krause, Volker Gaibler
At high redshift, extragalactic jets are associated with extended emission line regions. We present global and local hydrodynamic simulations of the interaction of jets with their…
Large-scale Propagation of Very Light Jets in Galaxy Clusters
V. Gaibler, M. Camenzind, M. Krause
We performed MHD simulations of very light bipolar jets with density contrasts down to 10^-4 in axisymmetry, which were injected into a medium of constant density and evolved up to…
Evolution of the ISM and Galactic Activity
Volker Gaibler, Max Camenzind, Martin Krause
We study the effects of time-dependent mass injection and heating on the evolution of the interstellar medium (ISM) in elliptical galaxies. As the large and luminous ellipticals ha…
