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. 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…
Characterisation of the Clouds' young stellar Bridge using Gaia DR3
Marie Schölch, Ãscar Jiménez-Arranz, Mercè Romero-Gómez +1
The interaction between the LMC and SMC (the Clouds) has resulted in prominent tidal features, including an extended bridge of gas and stars connecting the two galaxies. This Bridg…
From Gaia to GaiaNIR: II. A new view of the Milky Way bar
Ã. 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, Ãscar 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…
