Hydrodynamic Simulations of M51 and the interaction with NGC 5195
C. L. Dobbs, C. Theis, J. E. Pringle +1
The M51 galaxy is one of best examples of grand design structure in galaxies. The most likely origin of the spiral arms in M51 is the ongoing interaction with NGC 5195. Here we rep…
Substructures formation induced by gravitational tides?
F. Renaud, Ch. Theis, T. Naab +1
Physics lectures always refer to the tides as a disruptive effect. However, tides can also be compressive. When the potential of two galaxies overlap, as happens during a merger, f…
Starburst triggered by compressive tides in galaxy mergers
Florent Renaud, Christian Theis, Christian M. Boily
The tidal field of galaxies is known generally to be disruptive. However, in the case of galaxy mergers, a compressive mode of tidal wave may develop and last long enough to cocoon…
Towards an accurate model for the Antennae Galaxies
Simon J. Karl, Thorsten Naab, Peter H. Johansson +2
In the framework of hierarchical structure formation ellipticals can form from merging of smaller disk galaxies. The nearby interacting 'Antennae' galaxy pair (NGC 4038/39) is one…
Shape and orientation of stellar velocity ellipsoids in spiral galaxies
E. I. Vorobyov, Ch. Theis
We present a numerical study of the properties of the stellar velocity distribution in stellar discs which have developed a saturated, two-armed spiral structure. We follow the gro…
