r-Process Nucleosynthesis in Hot Accretion Disk Flows from Black Hole - Neutron Star Mergers
R. Surman, G. C. McLaughlin, M. Ruffert +2
We consider hot accretion disk outflows from black hole - neutron star mergers in the context of the nucleosynthesis they produce. We begin with a three dimensional numerical model…
Three-dimensional simulations of non-stationary accretion by remnant black holes of compact object mergers
S. Setiawan, M. Ruffert, H. -Th. Janka
(abridged) Three-dimensional hydrodynamic simulations with an Eulerian PPM code are presented for the time-dependent evolution of accretion tori around nonrotating and rotating ste…
Enrichment of the ICM of galaxy clusters due to ram-pressure stripping
W. Domainko, M. Mair, W. Kapferer +6
We investigate the impact of galactic mass loss triggered by ram-pressure stripping of cluster galaxies on the evolution of the intra-cluster medium (ICM). We use combined N-body a…
Metal Enrichment Processes in the Intra-Cluster Medium
S. Schindler, W. Kapferer, W. Domainko +7
We present numerical simulations of galaxy clusters which include interaction processes between the galaxies and the intra-cluster gas. The considered interaction processes are gal…
A fresh look at the unstable simulations of Bondi-Hoyle-Lyttleton accretion
T. Foglizzo, P. Galletti, M. Ruffert
The instability of Bondi-Hoyle-Lyttleton accretion, observed in numerical simulations, is analyzed through known physical mechanisms and possible numerical artefacts. The mechanism…
Non-stationary hyperaccretion of stellar-mass black holes in three dimensions: Torus evolution and neutrino emission
S. Setiawan, M. Ruffert, H. -Th. Janka
We present three-dimensional hydrodynamic simulations of the evolution of selfgravitating, thick accretion discs around hyperaccreting stellar-mass black holes. The black hole-toru…
