Invariant manifolds in barred galaxy simulations. II. Quantitative evidence of manifold-trapping in spiral arm formation
Toni Soler-Terricabras, Mercè Romero-Gómez, Santi Roca-Fàbrega
The main goal of this work is to quantify, through a robust methodology, the contribution of invariant manifolds to the formation of spiral arms in a pure N-body simulation, settin…
Arm morphology in off-centre barred galaxies
P. Sánchez-Martín, M. López-Vilamajó, M. Romero-Gómez +1
Many barred galaxies, including the Large Magellanic Cloud (LMC), display strong lopsidedness and off-centre bars. The dynamical connection between bar-disc misalignments, internal…
Warp evidences in precessing galactic bar models
Patricia Sanchez-Martin, Merce Romero-Gomez, Josep J. Masdemont
Most galaxies have a warped shape when they are seen from an edge-on point of view. The reason for this curious form is not completely known so far and in this work we apply dynami…
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…
Rings and spirals in barred galaxies. II. Ring and spiral morphology
E. Athanassoula, M. Romero-Gomez, A. Bosma +1
In this 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 gu…
Invariant manifolds as building blocks for the formation of spiral arms and rings in barred galaxies
M. Romero-Gomez, E. Athanassoula, J. J. Masdemont +1
We propose a theory to explain the formation of spiral arms and of all types of outer rings in barred galaxies, extending and applying the technique used in celestial mechanics to…
