Invariant manifolds in barred galaxy simulations. III. Self-regulated weakening of strong spiral arms
T. Soler-Terricabras, S. Roca-Fàbrega, M. Romero-Gómez
We investigated the origin of the weakening of strong spiral arms in barred galaxies, seeking the physical mechanism responsible for the decline in the fraction of manifold-trapped…
Invariant manifolds in barred galaxy simulations. I. Material density waves
Toni Soler-Terricabras, Mercè Romero-Gómez, Santi Roca-Fàbrega
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…
From Gaia to GaiaNIR: II. A new view of the Milky Way bar
Ó. Jiménez-Arranz, M. Schölch, S. Khanna +9
The Milky Way (MW) hosts a central bar whose pattern speed, orientation, and length remain uncertain, largely due to observational biases and selection effects, despite the transfo…
Asymmetries in the LMC velocity maps
Marie Schölch, Óscar Jiménez-Arranz, Mercè Romero-Gómez +4
The analysis of precise Gaia DR3 astrometry in the LMC region has revealed asymmetric patterns in the bar quadrupole and the disc outskirts of the LMC in-plane velocity maps. We ai…
Dark matter spiral arms in Milky Way-like halos
Marcel Bernet, Pau Ramos, Teresa Antoja +9
The coupling between the dark matter (DM) halo and the stellar disc is a key factor in galactic evolution. While the interaction between structures like the Galactic bar and DM hal…
