    • Gaia Data Release 2: Mapping the Milky Way disc kinematics 

      Katz, D.; Manteiga, Minia; Álvarez, M. A.; Arcay, Bernardino; Dafonte, Carlos; Garabato, D. (EDP Sciences, 2018)
      [Abstract] Context. The second Gaia data release (Gaia DR2) contains high-precision positions, parallaxes, and proper motions for 1.3 billion sources as well as line-of-sight velocities for 7.2 million stars brighter than ...

    • Gaia Data Release 3: Chemical cartography of the Milky Way 

      Recio-Blanco, A.; Garabato, D.; Álvarez, M. A.; Dafonte, Carlos; Gómez García, Ángel; González Santamaría, I.; Pallas-Quintela, Lara; Santoveña, Raúl; Silvelo, Arturo; Torralba Elipe, Guillermo; Manteiga, Minia (EDP Sciences, 2023-06)
      [Abstract]: Context. The motion of stars has been used to reveal details of the complex history of the Milky Way, in constant interaction with its environment. Nevertheless, to reconstruct the Galactic history puzzle in ...

    • Gaia Early Data Release 3: Acceleration of the Solar System from Gaia Astrometry 

      Manteiga, Minia; Álvarez, M. A.; Dafonte, Carlos; Garabato, D.; Gómez García, Ángel; González Santamaría, I.; Santoveña, Raúl (EDP Sciences, 2021)
      [Abstract] Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quality five-parameter astrometric ...

    • Gaia Early Data Release 3: The Galactic Anticentre 

      Manteiga, Minia; Álvarez, M. A.; Dafonte, Carlos; Garabato, D.; Gómez García, Ángel; González Santamaría, I.; Santoveña, Raúl (EDP Sciences, 2021)
      [Abstract] Aims. We aim to demonstrate the scientific potential of the Gaia Early Data Release 3 (EDR3) for the study of different aspects of the Milky Way structure and evolution and we provide, at the same time, a ...

    • Stellar ages, masses, extinctions, and orbital parameters based on spectroscopic parameters of Gaia DR3 

      Kordopatis, Georges; Schultheis, Mathias; McMillan, Paul J.; Palicio, Pedro Alonso; de Laverny, Patrick; Recio-Blanco, A.; Creevey, Orlagh; Álvarez, M. A.; Andrae, René; Poggio, Eloisa; Spitoni, Emanuele; Contursi, G.; Zhao, H.; Oreshina-Slezak, I.; Ordenovic, C.; Bijaoui, Albert (EDP Sciences, 2023)
      [Abstract]: Gaia's third data release provides radial velocities for 33 million stars and spectroscopically derived atmospheric parameters for more than 5 million targets. When combined with the astrometric data, these ...
