Morphologies arising from the gas flow in the innermost kiloparsec of barred galaxy models
Stavros Pastras, Panos A. Patsis, E. Athanassoula
Context. We study a series of response models to investigate the formation of specific morphological features in the central 1 kpc region of the gas component in barred spiral gala…
Loss of halo triaxiality due to bar formation
Rubens E. G. Machado, E. Athanassoula
Cosmological N-body simulations indicate that the dark matter haloes of galaxies should be generally triaxial. Yet, the presence of a baryonic disc is believed to alter the shape o…
Globular clusters and dwarf galaxies in Fornax - I. Kinematics in the cluster core from multi-object spectroscopy
G. Bergond, E. Athanassoula, S. Leon +6
We acquired radial velocities of a significant number of globular clusters (GCs) on wide fields between galaxies in the nearby Fornax cluster of galaxies, in order to derive their…
Orbital dynamics of three-dimensional bars: IV. Boxy isophotes in face-on views
P. A. Patsis, Ch Skokos, E. Athanassoula
We study the conditions that favour boxiness of isodensities in the face-on views of orbital 3D models for barred galaxies. Using orbital weighted profiles we show that boxiness is…
Orbital dynamics of three-dimensional bars: III. Boxy/Peanut edge-on profiles
P. A. Patis, Ch. Skokos, E. Athanassoula
We present families, and sets of families, of periodic orbits that provide building blocks for boxy and peanut (hereafter b/p) edge-on profiles. We find cases where the b/p profile…
Numerical Simulations of Interacting Gas-Rich Barred Galaxies
I. Berentzen, C. H. Heller, E. Athanassoula +1
Using an N-body+SPH code we have performed numerical simulations to investigate the dynamical effects of an interaction between an initially barred galaxy and a small spherical com…
