Gaia Focused Product Release: Radial velocity time series of long-period variables

Trabucchi, M.; 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 (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocity data planned with ...

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) ...

A Content-Based Approach to Profile Expansion

Fernández, Diego; Formoso, Vreixo; Cacheda, Fidel; Carneiro, Víctor (World Scientific, 2020-12)

[Abstract]: Collaborative Filtering algorithms suffer from the so-called cold-start problem. In particular, when a user has rated few items, recommendations offered by these algorithms are not too accurate. Profile Expansion ...

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: 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 ...

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 ...

Semantic Hierarchical Classification Applied to Anomaly Detection Using System Logs with a BERT Model

Corbelle, Clara; Carneiro, Víctor; Cacheda, Fidel (MDPI, 2024-06)

[Abstract]: The compaction and structuring of system logs facilitate and expedite anomaly and cyberattack detection processes using machine-learning techniques, while simultaneously reducing alert fatigue caused by false ...

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; 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 ...
