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…

The onset of stellar bars at Cosmic Noon. Bar-driven quenching and AGN co-evolution in a mature disc galaxy
Luca Costantin, Lorenzo Morelli, Cristina Cabello +15
The paper analyzes a barred spiral galaxy at redshift 1.17 using JWST NIRSpec data, showing that the bar formed early (z~5) and contributed to long‑term star‑formation quenching wh…
