Abstract:
Ground-based and space observations show that the nuclei of many
diskshaped galaxies are significantly offset from their geometric
center. This can lead to the excitation of the lopsided mode m=1. To
determine the dependence of this effect on the geometry of the system,
in this work we have compared a non-stationary disk model with respect
to the gravitational instabilities of the lopsided mode N=3; m=1
perturbation. In this work we have also compiled a summary catalog of
lopsided diskshaped galaxies and conducted a statistical analysis of
their physical parameters.
Description:
We have compiled a catalog of lopside galaxies whose nuclei are
shifted from their geometric center. The catalog contains a total of
2137 objects. We compiled the catalog using 37 articles.
