• 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 ...

• 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 ...

• 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 Focused Product Release: Spatial distribution of two diffuse interstellar bands 

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

  [Abstract] Diffuse interstellar bands (DIBs) are absorption features seen in optical and infrared spectra of stars and extragalactic objects that are probably caused by large and complex molecules in the galactic interstellar ...

• Gaia Focused Product Release: Sources from Service Interface Function image analysis: Half a million new sources in omega Centauri 

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

  [Abstract] Context. Gaia’s readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for nine selected regions ...
