Formation of asymmetric arms in barred galaxies
P. Sánchez-Martín, C. García-Gómez, J. J. Masdemont +1
We establish a dynamical mechanism to explain the origin of the asymmetry between the arms observed in some barred disk galaxies, where one of the two arms emanating from the bar e…
Application of a Neural Network classifier for the generation of clean Small Magellanic Cloud stellar samples
Ó. Jiménez-Arranz, M. Romero-Gómez, X. Luri +1
Context. Previous attempts to separate Small Magellanic Cloud (SMC) stars from the Milky Way (MW) foreground stars are based only on the proper motions of the stars. Aims. In this…
Kinematic analysis of the Large Magellanic Cloud using Gaia DR3
Ó. Jiménez-Arranz, M. Romero-Gómez, X. Luri +6
Context: The high quality of the Gaia mission data is allowing to study the internal kinematics of the Large Magellanic Cloud (LMC) in unprecedented detail, providing insights on t…
From ridges to manifolds: 3D characterization of the moving groups in the Milky Way disc
Marcel Bernet, Pau Ramos, Teresa Antoja +4
The stellar velocity distribution in the Solar Neighbourhood displays kinematic substructures, which are possibly signatures of the bar and spiral arms of the Milky Way and of prev…
A new resonance-like feature in the outer disc of the Milky Way
Ronald Drimmel, Shourya Khanna, Elena D'Onghia +18
Modern astrometric and spectroscopic surveys have revealed a wealth of structure in the phase space of stars in the Milky Way, with evidence of resonance features and non-equilibri…
The disturbed outer Milky Way disc
Paul J. McMillan, Jonathan Petersson, Thor Tepper-Garcia +9
The outer parts of the Milky Way's disc are significantly out of equilibrium. Using only distances and proper motions of stars from Gaia's Early Data Release 3, in the range |b|<10…
Deciphering the evolution of the Milky Way discs: Gaia APOGEE Kepler giant stars and the Besançon Galaxy Model
N. Lagarde, C. Reylé, C. Chiappini +13
We investigate the properties of the double sequences of the Milky Way discs visible in the [/Fe] vs [Fe/H] diagram. In the framework of Galactic formation and evolution, we dis…
On the Milky Way spiral arms from open clusters in Gaia EDR3
A. Castro-Ginard, P. J. McMillan, X. Luri +7
Context. The physical processes driving the formation of Galactic spiral arms are still under debate. Studies using open clusters favour the description of the Milky Way spiral arm…
Galactic spiral structure revealed by Gaia EDR3
E. Poggio, R. Drimmel, T. Cantat-Gaudin +14
Using the astrometry and integrated photometry from the Gaia Early Data Release 3 (EDR3), we map the density variations in the distribution of young Upper Main Sequence (UMS) stars…
Gaia Early Data Release 3: Structure and properties of the Magellanic Clouds
Gaia Collaboration, X. Luri, L. Chemin +417
We compare the Gaia DR2 and Gaia EDR3 performances in the study of the Magellanic Clouds and show the clear improvements in precision and accuracy in the new release. We also show…
Dynamical traceback age of the Pictoris moving group
N. Miret-Roig, P. A. B. Galli, W. Brandner +7
Context: The Pictoris moving group is one of the most well-known young associations in the solar neighbourhood and several members are known to host circumstellar discs, planet…
Dynamical Ages of the Young Local Associations with
Núria Miret-Roig, Teresa Antoja, Mercè Romero-Gómez +1
The Young Local Associations constitute an excellent sample for the study of a variety of astrophysical topics, especially the star formation process in low-density environments. D…
NGC 6705 a young -enhanced Open Cluster from OCCASO data
L. Casamiquela, R. Carrera, L. Balaguer-Núñez +12
The stellar [/Fe] abundance is sometimes used as a proxy for stellar age, following standard chemical evolution models for the Galaxy, as seen by different observational results…
The young open cluster NGC 7067 using Strömgren photometry
M. Monguió, I. Negueruela, A. Marco +13
NGC 7067 is a young open cluster located in the direction between the first and the second Galactic quadrants and close to the Perseus spiral arm. This makes it useful for studies…
A novel method to bracket the corotation radius in galaxy disks: vertex deviation maps
Santi Roca-Fàbrega, Teresa Antoja, Francesca Figueras +3
We map the kinematics of stars in simulated galaxy disks with spiral arms using the velocity ellipsoid vertex deviation (l). We use test particle simulations, and for the first…
On the galaxy spiral arms' nature as revealed by rotation frequencies
Santi Roca-Fàbrega, Octavio Valenzuela, Francesca Figueras +4
High resolution N-body simulations using different codes and initial condition techniques reveal two different behaviours for the rotation frequency of transient spiral arms like s…
Understanding the spiral structure of the Milky Way using the local kinematic groups
T. Antoja, F. Figueras, M. Romero-Gómez +3
We study the spiral arm influence on the solar neighbourhood stellar kinematics. As the nature of the Milky Way (MW) spiral arms is not completely determined, we study two models:…
