Closing the gap to convergence of gravitoturbulence in local simulations
Jannes Klee, Tobias F. Illenseer, Manuel Jung +1
Aims. Our goal is to find a converged cooling limit for fragmentation in self-gravitating disks. This is especially interesting for the formation of planets, brown dwarfs or stars…
Multi-scale simulations of black hole accretion in barred galaxies: Self-gravitating disk models
Manuel Jung, Tobias F. Illenseer, Wolfgang J. Duschl
Due to the non-axisymmetric potential of the central bar, barred spiral galaxies form, in addition to their characteristic arms and bar, a variety of structures within the thin gas…
Multi-scale simulations of black hole accretion in barred galaxies: Numerical methods and tests
Manuel Jung, Tobias F. Illenseer, Wolfgang J. Duschl
Due to the non-axisymmetric potential of the central bar, barred spiral galaxies form, in addition to their characteristic arms and bar, a variety of structures within the thin gas…
The impact of numerical oversteepening on the fragmentation boundary in self-gravitating disks
Jannes Klee, Tobias F. Illenseer, Manuel Jung +1
Context. It is still an open issue whether a self-gravitating accretion disk fragments. There are many different physical and numerical explanations for fragmentation, but simulati…
Self-similar solutions to isothermal shock problems
Stephan C. Deschner, Tobias F. Illenseer, Wolfgang J. Duschl
We investigate exact solutions for isothermal shock problems in different one-dimensional geometries. These solutions are given as analytical expressions if possible, or are comput…
Viscous time lags between starburst and AGN activity
Marvin Blank, Wolfgang J. Duschl
There is strong observational evidence indicating a time lag of order of some 100 Myr between the onset of starburst and AGN activity in galaxies. Dynamical time lags have been inv…
