Abstract
The association between galaxies is a phenomenon frequently occurring in the universe. Systems called Polar Ring Galaxies (PRGs) can be built for certain interactions. These structures consist of a galaxy known as a host and a ring of gas and stars surrounding a plane nearly perpendicular to its main axis. This research has contributed to the creation of a first library of N-body simulations, to study the parameters required to construct PRGs. A library of this kind is continuously expanding with new simulations based on these first findings. The inherent secular processes of isolated galaxies cannot give rise to this PRG geometry. Such systems are (i) created by galaxy interactions or (ii) by the introduction of cold gas from interstellar filaments within a galaxy. The most popular mechanisms are thought to be (i), and we are interested in this project, particularly where gas from one galaxy to another is introduced, without the need for a fusion. For formation of interaction, orbits with particular geometries are required in order to attach matter to form a polar ring. We review various mass ratios, inclinations and orbital energies in our society. The database which will be developed with the simulation results will contribute to future research on the interaction between galaxies, especially polar rings.
