Invariant manifolds in barred galaxy simulations. III. Self-regulated weakening of strong spiral arms
T. Soler-Terricabras, S. Roca-Fà brega, M. Romero-Gómez
The paper investigates why strong spiral arms in barred galaxies weaken, showing that self‑gravitating spirals shift the galaxy’s Lagrangian points, disrupting invariant‑manifold d…
Invariant manifolds in barred galaxy simulations. II. Quantitative evidence of manifold-trapping in spiral arm formation
Toni Soler-Terricabras, Mercè Romero-Gómez, Santi Roca-Fà brega
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…
Invariant manifolds in barred galaxy simulations. I. Material density waves
Toni Soler-Terricabras, Mercè Romero-Gómez, Santi Roca-Fà brega
We investigate the dynamical origin and kinematic signatures of spiral structure in an N-body simulation of an isolated barred galaxy, assessing whether invariant manifold theory p…
