Global MHD Modelling of the ISM - From large towards small scale turbulence
Miguel A. de Avillez, Dieter Breitschwerdt
Dealing numerically with the turbulent nature and non-linearity of the physical processes involved in the ISM requires the use of sophisticated numerical schemes coupled to HD and…
Disk-Halo-Disk Circulation and the Evolution of the ISM - 3D HD and MHD Adaptive Mesh Refinement Simulations
M. A. de Avillez, Dieter Breitschwerdt
State of the art models of the ISM use adaptive mesh refinement to capture small scale structures, by refining on the fly those regions of the grid where density and pressure gradi…
Weak ferromagnetism and spiral spin structures in honeycomb Hubbard planes
M A N Araujo, N M R Peres
Within the Hartree Fock- RPA analysis, we derive the spin wave spectrum for the weak ferromagnetic phase of the Hubbard model on the honeycomb lattice. Assuming a uniform magnetiza…
Ovi Column Density Distribution in the Local Bubble - Results from 3D Adaptive Mesh Refinement Simulations
Miguel A. de Avillez, Dieter Breitschwerdt
The Local Bubble (LB) is an X-ray emitting region extending 100 pc in radius in the Galactic plane and 300 pc perpendicular to it, and it is embedded in a somewhat larger H{\sc i}…
Keynote Lecture: Galactic and Extragalactic Bubbles
D. Breitschwerdt, M. A. de Avillez, M. J. Freyberg
The observational and theoretical state of Galactic and extragalactic bubbles are reviewed. Observations of superbubbles are discussed, with some emphasis on nearby bubbles such as…
3D Simulations of the Local Bubble
Dieter Breitschwerdt, Miguel A. de Avillez
We have performed high resolution 3D simulations of the Local Bubble (with 1.25 pc finest resolution) in a realistic background ISM, jointly with the dynamical evolution of the nei…
