Dynamical models of the elliptical galaxy NGC 4494
S. A. Rodionov, E. Athanassoula
We present dynamical models of NGC 4494, which we built using our iterative method presented in a previous paper. These models are live N-body models consisting of equal mass parti…
An expanded M_bh-sigma diagram, and a new calibration of active galactic nuclei masses
Alister W. Graham, Christopher A. Onken, E. Athanassoula +1
[Abridged] We present an updated and improved M_bh-sigma diagram containing 64 galaxies for which M_bh measurements (not just upper limits) are available. Due to new and increased…
Rings and spirals in barred galaxies. III. Further comparisons and links to observations
E. Athanassoula, M. Romero-Gomez, A. Bosma +1
In a series of papers, we propose a theory to explain the formation and properties of rings and spirals in barred galaxies. The building blocks of these structures are orbits guide…
