Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry

Manteiga, Minia; Álvarez, M. A.; Santoveña, Raúl; Panuzzo, P.; Pallas-Quintela, Lara; Garabato, D.; Gómez García, Ángel; Dafonte, Carlos; González Santamaría, I.; Torralba Elipe, Guillermo; Župić, Andrija (EDP Sciences, 2024)

[Abstract] Context. Gravitational waves from black-hole (BH) merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected based on most stellar ...

Data-Driven Early Academic Intervention: Harnessing AI for Students Achievement

Cacheda, Fidel; López-Vizcaíno, Manuel F.; Fernández, Diego; Carneiro, Víctor (International Journal of Information and Education Technology, 2024)

[Abstract]: In the dynamic landscape of higher education, the timely identification and mitigation of factors contributing to academic failure among university students are paramount for fostering academic success and ...

Efficient Execution of Web Navigation Sequences

Losada Pérez, José; Raposo Santiago, Juan; Pan Bermúdez, Carlos Alberto; Montoto, Paula (Springer, 2012)

[Abstract] Web automation applications are widely used for different purposes such as B2B integration and automated testing of web applications. Most current systems build the automatic web navigation component by using ...

Gaia Focused Product Release: Asteroid orbital solution: Properties and assessment

Mignard, François; David, P.; Manteiga, Minia; Garabato, D.; Álvarez, M. A.; Dafonte, Carlos; Gómez García, Ángel; González Santamaría, I.; Torralba Elipe, Guillermo (EDP Sciences, 2023)

[Abstract] Context. We report the exploitation of a sample of Solar System observations based on data from the third Gaia Data Release (Gaia DR3) of nearly 157 000 asteroids. It extends the epoch astrometric solution over ...

Gaia Data Release 3: Summary of the content and survey properties

Vallenari, A.; Manteiga, Minia; Garabato, D.; Álvarez, M. A.; Dafonte, Carlos; Gómez García, Ángel; González Santamaría, I.; Torralba Elipe, Guillermo (EDP Sciences, 2023)

[Abstract] Context. We present the third data release of the European Space Agency’s Gaia mission, Gaia DR3. This release includes a large variety of new data products, notably a much expanded radial velocity survey and a ...

Network Data Flow Clustering based on Unsupervised Learning

López-Vizcaíno, Manuel F.; Dafonte, Carlos; Nóvoa, Francisco; Garabato, D.; Álvarez, M. A.; Fernández, Diego (Institute of Electrical and Electronics Engineers Inc., 2019)

[Abstract]: Network communication data analysis is crucial in order to provide an adequate security level in computer infrastructures. As the volume of data and the number of features rise, the difficulties associated with ...

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 Data Release 2: Observations of solar system objects
