Gaia Focused Product Release: A catalogue of sources around quasars to search for strongly lensed quasars
(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 ... -
Methodology for obtaining the relative orbit and individual masses of Gaia astrometric binaries
(EDP Sciences, 2024-02)[Abstract]: Context. The recent Gaia Data Release 3 has revealed a catalogue of more than eight hundred thousand binary systems. The release provides orbital solutions for half of the systems, with the majority of them ... -
On the estimation of stellar parameters with uncertainty prediction from Generative Artificial Neural Networks: application to Gaia RVS simulated spectra
(EDP Sciences, 2016-10)[Abstract]: Aims. We present an innovative artificial neural network (ANN) architecture, called Generative ANN (GANN), that computes the forward model, that is it learns the function that relates the unknown outputs (stellar ...
