Can dust destabilize galactic disks?
Ch. Theis, N. Orlova
We studied the dynamical influence of a dust component on the gaseous phase in central regions of galactic disks. Therefore, we performed two-dimensional hydrodynamical simulations…
Chemodynamical Modeling of Dwarf Galaxy Evolution
P. Berczik, G. Hensler, Ch. Theis +1
We present our recently developed 3-dimensional chemodynamical code for galaxy evolution. It follows the evolution of all components of a galaxy such as dark matter, stars, molecul…
Test of molecular mode coupling theory: A first resume
C. Theis, F. Sciortino, A. Latz +2
We report recent progress on the test of mode coupling theory for molecular liquids (MMCT) for molecules of arbitrary shape. The MMCT equations in the long time limit are solved fo…
On the evolution of shape in N-body simulations
Ch. Theis, R. Spurzem
A database on shape evolution of direct N-body models formed out of cold, dissipationless collapse is generated using GRAPE and HARP special purpose computers. Such models are impo…
Neutron scattering in molecular liquids: Influence of orientational degrees of freedom and the prepeak in a fragile glass former
Christoph Theis, Rolf Schilling
The intermediate scattering function S(q,t) for neutron scattering is expanded with respect to a complete set of correlation functions which describe the dynamical correlations in…
Condensation and Evaporation of Interstellar Clouds in Chemodynamical Models of Galaxies
J. K"oppen, Ch. Theis, G. Hensler
The network of interactions between hot gas, cool clouds, massive stars, and stellar remnants used in the chemodynamical modeling of the interstellar medium is investigated for the…
