Linking dynamics and chemistry in barred galaxies through action-space mapping
Tetsuro Asano, Victor P. Debattista, Michiko S. Fujii
We aim to extend the action-based framework, proposed by a previous study, for assigning chemical information to collisionless -body simulations of barred galaxies, enabling mor…
Chemodynamical evidence of the HR 1614 moving group as a bar resonance
Andreas J. Koch-Hansen, Vladislav Gulaev, Dominik H. Plonka +4
The study combines high‑resolution spectroscopy of six HR 1614 moving‑group stars with orbital frequency analysis to show that the group’s diverse ages and chemical patterns are be…
Composite Bulges -- V. Detecting signatures of gas inflows in IFU data: The MUSE view of ionised gas kinematics in nearby galaxies
Tutku Kolcu, Witold Maciejewski, Peter Erwin +7
Using VLT/MUSE data, we study the ionised-gas kinematics in a mass- and volume-limited (, \,Mpc) sample of 21 nearby galaxies to identify signa…
GASTRO library II: Exploring Chemical Bimodalities in Disk Galaxies with GSE-like Mergers and Massive Star-forming Clumps
João A. S. Amarante, Chervin F. P. Laporte, Victor P. Debattista +10
We use several smoothed particle hydrodynamics+N-body models as part of the GASTRO library to study the role of high-density star-forming clumpy regions and a single merger on the…
Kinematic hints of a nuclear bar in the Milky Way
Karl Fiteni, Mattia C. Sormani, Victor P. Debattista +8
The Milky Way hosts a flattened nuclear stellar disc (NSD) that dominates the gravitational potential in the inner few hundred parsecs. Whether the NSD is purely axisymmetric or co…
The Low- Splash Population in the Milky Way
Lais Borbolato, João A. S. Amarante, Hélio D. Perottoni +5
The Milky Way in-situ halo, also known as the Splash, consists of old (Age 10 Gyr), metal-rich ([Fe/H] ), high- stars, i.e., thick disk-like chemistry, on halo-like…
