    • 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 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 ...
    • Oil spill segmentation in SAR images using convolutional neural networks. A comparative analysis with clustering and logistic regression algorithms 

      Cantorna Berdullas, Diego; Dafonte, Carlos; Iglesias, Alfonso; Arcay, Bernardino (Elsevier Ltd, 2019-11)
      [Abstract]: Synthetic aperture radar (SAR) images are a valuable source of information for the detection of marine oil spills. For their effective analysis, it is important to have segmentation algorithms that can delimit ...
    • Gaia Data Release 2: Observational Hertzsprung-Russell diagrams 

      Babusiaux, C.; Manteiga, Minia; Álvarez, M. A.; Arcay, Bernardino; Dafonte, Carlos; Garabato, D. (EDP Sciences, 2018)
      [Abstract] Context. Gaia Data Release 2 provides high-precision astrometry and three-band photometry for about 1.3 billion sources over the full sky. The precision, accuracy, and homogeneity of both astrometry and photometry ...
