Deep chemical tagging -- Identifying open clusters and moving groups in chemical space with graph attention networks
Lorenzo Spina, Milan Quandt Rodriguez, Laura Magrini +3
Reconstructing the formation history of the Milky Way is hindered by stellar migration, which erases kinematic birth signatures. In contrast, stellar chemical abundances remain sta…
Exploring substructures in the Milky Way halo Neural networks applied to Gaia and APOGEE DR 17
L. Berni, L. Spina, L. Magrini +3
The identification of stellar structures in the Galactic halo, including stellar streams and merger remnants, often relies on the dynamics of their constituent stars. However, this…
Kinematics of metallicity populations in Omega Centauri using Gaia Focused Product Release and Hubble Space Telescope
Nagaraj Vernekar, Sara Lucatello, Pete Kuzma +1
Context. Omega Cen is the largest known globular cluster in the Milky Way. It is also quite a complex object with a large metallicity spread and multiple stellar populations. Despi…
Gaia dr3 reveals the complex dynamical evolution within star clusters
C. Viscasillas Vázquez, L. Magrini, N. Miret-Roig +6
Context: Star clusters, composed of stars born from the same molecular cloud, serve as invaluable natural laboratories for understanding the fundamental processes governing stellar…
Parameter Estimation for Open Clusters using an Artificial Neural Network with a QuadTree-based Feature Extractor
L. Cavallo, L. Spina, G. Carraro +7
With the unprecedented increase of known star clusters, quick and modern tools are needed for their analysis. In this work, we develop an artificial neural network trained on synth…
Gaia Focused Product Release: A catalogue of sources around quasars to search for strongly lensed quasars
Gaia Collaboration, A. Krone-Martins, C. Ducourant +398
Context. Strongly lensed quasars are fundamental sources for cosmology. The Gaia space mission covers the entire sky with the unprecedented resolution of " in the optical, ma…
The role of radial migration in open cluster and field star populations with Gaia dr3
Carlos Viscasillas Vázquez, Laura Magrini, Lorenzo Spina +4
The survival time of a star cluster depends on its total mass, density, and thus size, as well as on the environment in which it was born and in which lies. Its dynamical evolution…
