    • Gaia Data Release 2: Observations of solar system objects 

      Manteiga, Minia; Spoto, F.; Álvarez, M. A.; Arcay, Bernardino; Dafonte, Carlos; Garabato, D. (EDP Sciences, 2018)
      [Abstract] Context. The Gaia spacecraft of the European Space Agency (ESA) has been securing observations of solar system objects (SSOs) since the beginning of its operations. Data Release 2 (DR2) contains the observations ...

    • Gaia Data Release 3: Catalogue validation 

      Babusiaux, C.; Álvarez, M. A.; Dafonte, Carlos; Manteiga, Minia; Santoveña, Raúl; Torralba Elipe, Guillermo (EDP Sciences, 2023-06)
      [Abstract]: Context. The third Gaia data release (DR3) provides a wealth of new data products. The early part of the release, Gaia EDR3, already provided the astrometric and photometric data for nearly two billion sources. ...

    • Gaia Data Release 3: Mapping the asymmetric disc of the Milky Way 

      Drimmel, Ronald; Manteiga, Minia; Garabato, D.; Álvarez, M. A.; Dafonte, Carlos; Gómez García, Ángel; González Santamaría, I.; Torralba Elipe, Guillermo (EDP Sciences, 2023)
      [Abstract] Context. With the most recent Gaia data release, the number of sources with complete 6D phase space information (position and velocity) has increased to well over 33 million stars, while stellar astrophysical ...

    • Gaia Data Release 3: Pulsations in main sequence OBAF-type stars 

      Ridder, Joris de; Manteiga, Minia; Garabato, D.; Álvarez, M. A.; Dafonte, Carlos; Gómez García, Ángel; González Santamaría, I.; Torralba Elipe, Guillermo (EDP Sciences, 2023)
      [Abstract] Context. The third Gaia data release provides photometric time series covering 34 months for about 10 million stars. For many of those stars, a characterisation in Fourier space and their variability classification ...

    • Gaia Data Release 3: Reflectance spectra of Solar System small bodies 

      Galluccio, L.; Manteiga, Minia; Garabato, D.; Álvarez, M. A.; Dafonte, Carlos; Gómez García, Ángel; González Santamaría, I.; Torralba Elipe, Guillermo (EDP Sciences, 2023)
      [Abstract] Context. The Gaia mission of the European Space Agency (ESA) has been routinely observing Solar System objects (SSOs) since the beginning of its operations in August 2014. The Gaia data release three (DR3) ...

    • Gaia Data Release 3: Stellar multiplicity, a teaser for the hidden treasure 

      Arenou, F.; Manteiga, Minia; Garabato, D.; Álvarez, M. A.; Dafonte, Carlos; Gómez García, Ángel; González Santamaría, I.; Torralba Elipe, Guillermo (EDP Sciences, 2023)
      [Abstract] Context. The Gaia DR3 catalogue contains, for the first time, about 800 000 solutions with either orbital elements or trend parameters for astrometric, spectroscopic, and eclipsing binaries, and combinations of ...

    • Gaia Focused Product Release: A catalogue of sources around quasars to search for strongly lensed quasars 

      Krone-Martins, A.; Garabato, D.; Álvarez, M. A.; Dafonte, Carlos; Gómez García, Ángel; González Santamaría, I.; Pallas-Quintela, Lara; Santoveña, Raúl Raúl; Torralba Elipe, Guillermo; Manteiga, Minia (EDP Sciences, 2024-05-17)
      [Abstract]: Context. Strongly lensed quasars are fundamental sources for cosmology. The Gaia space mission covers the entire sky with the unprecedented resolution of 0.18″ in the optical, making it an ideal instrument to ...
