Orbital Evolution of Binaries in Circumbinary Disks
Magdalena Siwek, Rainer Weinberger, Lars Hernquist
We present the to-date largest parameter space exploration of binaries in circumbinary disks (CBDs), deriving orbital evolution prescriptions for eccentric, unequal mass binaries f…
Preferential Accretion and Circumbinary Disk Precession in Eccentric Binary Systems
Magdalena Siwek, Rainer Weinberger, Diego Munoz +1
We present a suite of high resolution hydrodynamic simulations of binaries immersed in circumbinary accretion disks (CBDs). For the first time, we investigate the preferential accr…
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…
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…
